-/**
- * A <code>CompoundName</code> is a series of string elements, and it represents 
- * a name in a naming service within a single namespace. Typically these 
- * names have a structure which is hierarchical. 
- * <p>
- * A <code>CompoundName</code> has a sequence of zero or more elements delimited 
- * by the char specified in the property "jndi.syntax.separator". This property 
- * is required except when the direction of the name is "flat" 
- * (see jndi.syntax.direction). The property "jndi.syntax.separator2" allows for 
- * the specification of an additional separator. A separator string will be 
- * treated as normal characters if it is preceded by the escape string or is 
- * within quotes.</p>
- * <p>
- * The property "jndi.syntax.direction" specifies the direction in which the name
- * is read. Permitted values are "right_to_left", "left_to_right" and "flat". A 
- * flat name does not have a hierarchical structure. If this property is not 
- * specified then the default is "flat". If this property is specified with an 
- * invalid value then an <code>IllegalArgumentException</code> should be raised.</p>
- * <p>
- * Each element can be accessed using its position. The first element is at 
- * position 0. The direction of the name is important. When direction is 
- * "left_to_right" then the leftmost element is at position 0. Conversely when 
- * the direction is "right_to_left" then the rightmost element is at position 0.</p>
- * <p>
- * There are other properties which affect the syntax of a <code>CompoundName</code>. 
- * The following properties are all optional:
- * <ul>
- * <li>
- * jndi.syntax.escape -		Escape sequence,The escape sequence is used to escape 
- * 							a quote, separator or escape. When preceded itself by 
- * 							the escape sequence it is treated as ordinary characters.
- * 							When it is followed by chars which are not quote or 
- * 							separator strings then it is treated as ordinary characters</li>
- * <li>
- * jndi.syntax.beginquote -	Used as start of quoted string (Defaults to endquote)</li>
- * <li>
- * jndi.syntax.endquote - 	Used as end of quoted string (Defaults to beginquote)</li>
- * <li>
- * jndi.syntax.beginquote2 -	Additionally used as start of quoted string 
- * 							(Defaults to endquote2)</li>
- * <li>
- * jndi.syntax.endquote2 - 	Additionally used as end of quoted string 
- * 							(Defaults to beginquote2)</li>
- * </ul>
- * <p>
- * When a non-escaped quote appears at the start of an element it must be matched at the
- * end. That element can then be said to be quoted. When an escape sequence appears
- * within a quoted element then it is treated as normal characters unless it precedes
- * an occurrence of the quote in which case it is assumed that the quoted element
- * contains a quote which is escaped.</p>
- * <p>
- * If the element does not start with a quote, then any quote strings within that
- * element are just normal characters.</p>
- * <p>
- * <ul>
- * <li>
- * jndi.syntax.ignorecase -	If 'true' then ignore case when name elements are compared.
- *  						If false or not set then case is important.</li>
- * <li>
- * jndi.syntax.trimblanks -	If 'true' then ignore leading & trailing blanks when name elements are compared.
- * 							If false or not set then blanks are important.</li>
- * </ul></p>
- * <p>
- * These 2 properties relate to names where the syntax includes attribute/content 
- * pairs.
- * <ul>
- * <li>jndi.syntax.separator.ava</li>
- * <li>jndi.syntax.separator.typeval</li>
- * </ul>
- * For example the LDAP name, "CN=Mandy Jennings, O=Apache, C=UK".
- * In this example the pair separator jndi.syntax.separator.ava is ',', and the 
- * character that separates pairs jndi.syntax.separator.typeval is '='. See 
- * RFC1779 for LDAP naming conventions.</p>
- * <p>
- * The jndi.syntax.separator.ava is not used when manipulating <code>CompoundName</code>. 
- * The jndi.syntax.separator is still used to separate elements.</p>
- * <p>
- * The <code>CompoundName</code> needs to be aware of the jndi.syntax.separator.typeval
- * in case of the instance where a quoted string is used to provide the content
- * of a pair.</p>
- * <p>
- * Consider the string "CN=$Mandy Jennings, O=Apache, C=UK" with
- * <ul>
- * <li>
- * jndi.syntax.direction         set to "right_to_left"</li>
- * <li>
- * jndi.syntax.separator         set to ","</li>
- * <li>
- * jndi.syntax.separator.typeval set to "="</li>
- * </ul>
- * When no jndi.syntax.beginquote is set then this creates a valid <code>CompoundName</code>
- * with 3 elements.</p>
- * <p>
- * If jndi.syntax.beginquote is then set to "$" the name becomes invalid as the
- * content part of the pair CN=$Mandy Jennings has a mismatched quote.</p>
- * <p>
- * The string "CN=$Mandy Jennings$, O=Apache, C=UK" would be fine as the $ quotes
- * round Mandy Jennings now balance.</p>
- * <p>
- * A <code>CompoundName</code> may be empty. An empty <code>CompoundName</code> has no elements.
- * Elements may also be empty.</p> 
- * 
- * <pre>
- * Some Examples:
- * ==============
- * 
- * Consider the following compound name from the file system namespace:
- *     "home/jenningm-abc/.profile" 
- * 
- * jndi.syntax.separator is set to '/' as in the UNIX filesystem.
- * This name has 3 elements:
- *     home jenningm-abc and .profile
- * The direction should be left_to_right as in the UNIX filesystem
- * The element at position 0 would be home.
- * 
- * 
- * Consider if jndi.syntax.separator had been set to '-' then this name 
- * would have 2 elements:
- *     home/jenningm and abc/.profile
- * If the direction was right_to_left then the element at position 0
- * would be abc/.profile.
- * 
- * Consider the name "&lt;ab&lt;cd&gt;ef&gt;" where jndi.syntax.beginquote is &lt;
- * and jndi.syntax.endquote is &gt;. This will give rise to an 
- * InvalidNameException because a close quote was encountered before
- * the end of an element. The same is also true for "&lt;abcd&gt;ef&gt;".
- * If the name was "ab&lt;cd&gt;ef" then this would be valid and there would
- * be one element ab&lt;cd&gt;ef.
- * However if the name was "&lt;abcdef&gt;" there would be one element abcdef.
- * 
- * An empty <code>CompoundName</code> is the name "" and has no elements.
- * 
- * When jndi.syntax.beginquote is set to " and beginquote2 is set to '
- * the behaviour is simliar to CompositeName - 
- * The name "\"abcd" gives an InvalidNameException as there is no closing quote.
- * The name "'\"abcd'" gives one element of value "abcd.
- * The name "\\abcd" gives one element of value \abcd. 
- *  
- * Assuming:
- *     jndi.syntax.separator is "/"
- *     jndi.syntax.direction is "left_to_right"
- * then
- *     "" is empty. It has no elements.
- *     "/" has one empty element.
- *     "//" has 2 empty elements.
- *     "/a/" has 3 elements the middle one is set to a.
- *     "///" has 3 empty elements.
- *     "//a/" has 4 elements, the last but one is set to a.
- * 
- *
- * Assuming the only properties set are: 
- *     jndi.syntax.separator is "/"
- *     jndi.syntax.direction is "left_to_right"
- * then the String
- *     "\"" has one element with the value "
- *     "\\\"" has one element with the value \"
- *     "\\\"'" has one element with the value \"'
- * 
- * Assuming the only properties set are:
- *     jndi.syntax.separator is "/"
- *     jndi.syntax.direction is "left_to_right"
- *     jndi.syntax.beginquote is "\""
- * 
- * then the String
- *     "\"" is invalid because of no closing quote
- *     "\\\"" has one element with the value \"
- *     "\\\"'" has one element with the value \"'
- * 
- * 
- * Assuming the only properties set are:
- *     jndi.syntax.separator is "/"
- *     jndi.syntax.direction is "left_to_right"
- *     jndi.syntax.beginquote is "\""
- *     jndi.syntax.beginquote2 is "\'"
- * then the String
- *     "\"" is invalid because of no closing quote
- *     "\\\"" has one element with the value \"
- *     "\\\"'" has one element with the value \"'
- *     "'\\" is invalid because of no closing quote
- * </pre>

+/**
+ * A <code>CompoundName</code> is a series of string elements, and it represents 
+ * a name in a naming service within a single namespace. Typically these 
+ * names have a structure which is hierarchical. 
+ * <p>
+ * A <code>CompoundName</code> has a sequence of zero or more elements delimited 
+ * by the char specified in the property "jndi.syntax.separator". This property 
+ * is required except when the direction of the name is "flat" 
+ * (see jndi.syntax.direction). The property "jndi.syntax.separator2" allows for 
+ * the specification of an additional separator. A separator string will be 
+ * treated as normal characters if it is preceded by the escape string or is 
+ * within quotes.</p>
+ * <p>
+ * The property "jndi.syntax.direction" specifies the direction in which the name
+ * is read. Permitted values are "right_to_left", "left_to_right" and "flat". A 
+ * flat name does not have a hierarchical structure. If this property is not 
+ * specified then the default is "flat". If this property is specified with an 
+ * invalid value then an <code>IllegalArgumentException</code> should be raised.</p>
+ * <p>
+ * Each element can be accessed using its position. The first element is at 
+ * position 0. The direction of the name is important. When direction is 
+ * "left_to_right" then the leftmost element is at position 0. Conversely when 
+ * the direction is "right_to_left" then the rightmost element is at position 0.</p>
+ * <p>
+ * There are other properties which affect the syntax of a <code>CompoundName</code>. 
+ * The following properties are all optional:
+ * <ul>
+ * <li>
+ * jndi.syntax.escape -		Escape sequence,The escape sequence is used to escape 
+ * 							a quote, separator or escape. When preceded itself by 
+ * 							the escape sequence it is treated as ordinary characters.
+ * 							When it is followed by chars which are not quote or 
+ * 							separator strings then it is treated as ordinary characters</li>
+ * <li>
+ * jndi.syntax.beginquote -	Used as start of quoted string (Defaults to endquote)</li>
+ * <li>
+ * jndi.syntax.endquote - 	Used as end of quoted string (Defaults to beginquote)</li>
+ * <li>
+ * jndi.syntax.beginquote2 -	Additionally used as start of quoted string 
+ * 							(Defaults to endquote2)</li>
+ * <li>
+ * jndi.syntax.endquote2 - 	Additionally used as end of quoted string 
+ * 							(Defaults to beginquote2)</li>
+ * </ul>
+ * <p>
+ * When a non-escaped quote appears at the start of an element it must be matched at the
+ * end. That element can then be said to be quoted. When an escape sequence appears
+ * within a quoted element then it is treated as normal characters unless it precedes
+ * an occurrence of the quote in which case it is assumed that the quoted element
+ * contains a quote which is escaped.</p>
+ * <p>
+ * If the element does not start with a quote, then any quote strings within that
+ * element are just normal characters.</p>
+ * <p>
+ * <ul>
+ * <li>
+ * jndi.syntax.ignorecase -	If 'true' then ignore case when name elements are compared.
+ *  						If false or not set then case is important.</li>
+ * <li>
+ * jndi.syntax.trimblanks -	If 'true' then ignore leading & trailing blanks when name elements are compared.
+ * 							If false or not set then blanks are important.</li>
+ * </ul></p>
+ * <p>
+ * These 2 properties relate to names where the syntax includes attribute/content 
+ * pairs.
+ * <ul>
+ * <li>jndi.syntax.separator.ava</li>
+ * <li>jndi.syntax.separator.typeval</li>
+ * </ul>
+ * For example the LDAP name, "CN=Mandy Jennings, O=Apache, C=UK".
+ * In this example the pair separator jndi.syntax.separator.ava is ',', and the 
+ * character that separates pairs jndi.syntax.separator.typeval is '='. See 
+ * RFC1779 for LDAP naming conventions.</p>
+ * <p>
+ * The jndi.syntax.separator.ava is not used when manipulating <code>CompoundName</code>. 
+ * The jndi.syntax.separator is still used to separate elements.</p>
+ * <p>
+ * The <code>CompoundName</code> needs to be aware of the jndi.syntax.separator.typeval
+ * in case of the instance where a quoted string is used to provide the content
+ * of a pair.</p>
+ * <p>
+ * Consider the string "CN=$Mandy Jennings, O=Apache, C=UK" with
+ * <ul>
+ * <li>
+ * jndi.syntax.direction         set to "right_to_left"</li>
+ * <li>
+ * jndi.syntax.separator         set to ","</li>
+ * <li>
+ * jndi.syntax.separator.typeval set to "="</li>
+ * </ul>
+ * When no jndi.syntax.beginquote is set then this creates a valid <code>CompoundName</code>
+ * with 3 elements.</p>
+ * <p>
+ * If jndi.syntax.beginquote is then set to "$" the name becomes invalid as the
+ * content part of the pair CN=$Mandy Jennings has a mismatched quote.</p>
+ * <p>
+ * The string "CN=$Mandy Jennings$, O=Apache, C=UK" would be fine as the $ quotes
+ * round Mandy Jennings now balance.</p>
+ * <p>
+ * A <code>CompoundName</code> may be empty. An empty <code>CompoundName</code> has no elements.
+ * Elements may also be empty.</p> 
+ * 
+ * <pre>
+ * Some Examples:
+ * ==============
+ * 
+ * Consider the following compound name from the file system namespace:
+ *     "home/jenningm-abc/.profile" 
+ * 
+ * jndi.syntax.separator is set to '/' as in the UNIX filesystem.
+ * This name has 3 elements:
+ *     home jenningm-abc and .profile
+ * The direction should be left_to_right as in the UNIX filesystem
+ * The element at position 0 would be home.
+ * 
+ * 
+ * Consider if jndi.syntax.separator had been set to '-' then this name 
+ * would have 2 elements:
+ *     home/jenningm and abc/.profile
+ * If the direction was right_to_left then the element at position 0
+ * would be abc/.profile.
+ * 
+ * Consider the name "&lt;ab&lt;cd&gt;ef&gt;" where jndi.syntax.beginquote is &lt;
+ * and jndi.syntax.endquote is &gt;. This will give rise to an 
+ * InvalidNameException because a close quote was encountered before
+ * the end of an element. The same is also true for "&lt;abcd&gt;ef&gt;".
+ * If the name was "ab&lt;cd&gt;ef" then this would be valid and there would
+ * be one element ab&lt;cd&gt;ef.
+ * However if the name was "&lt;abcdef&gt;" there would be one element abcdef.
+ * 
+ * An empty <code>CompoundName</code> is the name "" and has no elements.
+ * 
+ * When jndi.syntax.beginquote is set to " and beginquote2 is set to '
+ * the behaviour is simliar to CompositeName - 
+ * The name "\"abcd" gives an InvalidNameException as there is no closing quote.
+ * The name "'\"abcd'" gives one element of value "abcd.
+ * The name "\\abcd" gives one element of value \abcd. 
+ *  
+ * Assuming:
+ *     jndi.syntax.separator is "/"
+ *     jndi.syntax.direction is "left_to_right"
+ * then
+ *     "" is empty. It has no elements.
+ *     "/" has one empty element.
+ *     "//" has 2 empty elements.
+ *     "/a/" has 3 elements the middle one is set to a.
+ *     "///" has 3 empty elements.
+ *     "//a/" has 4 elements, the last but one is set to a.
+ * 
+ *
+ * Assuming the only properties set are: 
+ *     jndi.syntax.separator is "/"
+ *     jndi.syntax.direction is "left_to_right"
+ * then the String
+ *     "\"" has one element with the value "
+ *     "\\\"" has one element with the value \"
+ *     "\\\"'" has one element with the value \"'
+ * 
+ * Assuming the only properties set are:
+ *     jndi.syntax.separator is "/"
+ *     jndi.syntax.direction is "left_to_right"
+ *     jndi.syntax.beginquote is "\""
+ * 
+ * then the String
+ *     "\"" is invalid because of no closing quote
+ *     "\\\"" has one element with the value \"
+ *     "\\\"'" has one element with the value \"'
+ * 
+ * 
+ * Assuming the only properties set are:
+ *     jndi.syntax.separator is "/"
+ *     jndi.syntax.direction is "left_to_right"
+ *     jndi.syntax.beginquote is "\""
+ *     jndi.syntax.beginquote2 is "\'"
+ * then the String
+ *     "\"" is invalid because of no closing quote
+ *     "\\\"" has one element with the value \"
+ *     "\\\"'" has one element with the value \"'
+ *     "'\\" is invalid because of no closing quote
