[jboss-dev] jaxen in AS

[Alejandro Guizar]

dom4j also uses jaxen to provide xpath features. Don't know if any other 
component in AS uses xpath, tough.

Re: declaring dependencies, how far a component should go? jbpm-bpel 
uses hibernate. In turn, hibernate uses cglib (among other stuff). 
jbpm-bpel does not use cglib directly, but will not run if cglib is not 
present. Should jbpm-bpel declare cglib?
