-<h3>Building OM from Objects - Use of ObjectToOMBuilder</h3>
-<p>
-There is a requirement to build an OM with a given object structure. A Typical scenario will
be to build OM from an object structure that is returned from a data binding tool. So when
the need arises to generate an OM from an object, a special builder class is to be used. The
ObjectToOMBuilder class implements the XMLParserWrapper  (which is effectively the builder
interface), but unlike the other builders such a conversion cannot be pull based. It is “push
based&quot; which means that the builder should have access to a content handler in order
to push events. Hence the ObjectToOmBuilder implements the registerContentHandler method which
accepts an instance of the SAX ContentHandler.interface.
-In serializing however the user need not worry whether the inner parts of the OM tree consists
of Object builders which are push based. The serializing mechanism automatically registers
a StreamToContentHandlerConverter which effectively redirects all the ContentHandler events
into the relevant XMLStreamWriter. 
-The ObjectToOMBuilder expects an org.apache.axis.om.OutObject interface from the third party
for registering a SAX ContentHandler. The ObjctToOMBuilder should also be supplied with the
parent element which the supplied object should be serialized under. When the ObjectToOMBuilder
is asked to proceed the call is in turn passed to the OutObject to fire SAX events. The ObjectToOMBuilder
will take care of building the structure (if needed).</p>

-<p>The following code segment explains this scenario.</p>
-<pre class="code">
-// create the parent element
-OMFactory omFactory = OMAbstractFactory.getOMFactory();
-OMNamespace ns = omFactory.createOMNamespace(SOAP11Constants.SOAP_ENVELOPE_NAMESPACE_URI,
SOAP11Constants.SOAP_DEFAULT_NAMESPACE_PREFIX);<br>element = omFactory.createOMElement("Body",
ns);
-
-OutObject outObject = // get the third party object here
-new ObjectToOMBuilder(element,outObject).next();
-</pre>

 <h2>Section 4 - Known Limitations of OM</h2>
 <h3>Incomplete XML Info set support</h3>
 <p>The OM deliberately dropped the support for XML info set items such as DTDs and
 Processing Instructions (PI's). Hence the OM cannot be called a complete info set representation.
The initial reason for this was because the design goal of the OM was not to be "yet-another-object-model"
but to be a SOAP specific Object model. Since DTD's and PI's are not supposed to be present
in SOAP messages.</p>
