Source of XPath selectors
Documentation (http://activemq.apache.org/selectors.html) states the
following:
" Using XPath to filter messages
Apache ActiveMQ also supports XPath based selectors when working with
messages containing XML bodies. To use an XPath selector use the following
syntax
XPATH '//title[@lang=''eng'']' "
Is this in support of XPath 1.0 or XPath 2.0.... also what library supports
this? Xalan, Saxon, etc... I didn't see an XPath library in the libs folder
or subfolders.
Thanks!

Thanks for the info!
I created this JIRA issue for an enhancement request of XPath 2.0 support:
Add XPath 2.0 support to ActiveMQ
https://issues.apache.org/jira/browse/AMQ-3151
Thanks,
Robert

there are no plans at the moment, the use of the Xalan xpath api is
plugable and we love contributions :-) - see:
http://svn.apache.org/viewvc/activemq/trunk/activemq-core/src/main/java/org/apache/activemq/filter/XPathExpression.java?view=markup
For a start, raise an enhancement jira for xpath 2.0 support so it is not lost.
re: the jars in optional, I think the main motivator is reducing a few
meg from the distribution. it has not been shipped since 2006

Great Gary, thanks for the info!
Any plans to go to Xalan 2.7.1 or selectively decide between XPath 1.0
(Xalan) and XPath 2.0 (e.g., Saxon)?
Also, why don't I see the Xalan JAR under the lib folder/subfolders?

It requires xalan, trunk currently tests against version 2.6.0
