----------------------------------

Hi Sam,

I've worked on it some more and I figured out how to get it work as I originally proposed.  The latest snapshot should have the enhancement.  The full list of XML attributes supported is listed at:

http://activemq.apache.org/apollo/versions/1.0-SNAPSHOT/website/documentation/user-manual.html#Stomp_Protocol_Options

> When using a character other than a period as a topic separator (.), Apollo throws the following exception:
> {code} 
> org.apache.activemq.apollo.util.path.PathParser$PathException: Invalid destination path part: 'event/abc', it does not match regex: [a-zA-Z0-9\_\-\%\~]+
> {code}
> In the example, we're using {{/topic/event/abc}} as a topic. In {{[PathParser.java|http://svn.apache.org/viewvc/activemq/activemq-apollo/trunk/apollo-util/src/main/scala/org/apache/activemq/apollo/util/path/PathParser.java?view=markup]}}, line 47 determines that {{path_seperator = new AsciiBuffer(".")}}. Thus, Apollo incorrectly tokenizes the topic and so {{event/abc}} fails the regular expression on line 48 of the same file.
> In short, it should be possible to specify what the topic separator is, or (even better) detect when a different character is being used as a delimiter.
