As my email mentions, it should be a matter of creating a .xsd that maps
to the DESCR AST - which XMLBeans can then use. Unless someone in the
community picks this up, its unlikely to make it into 3.0.

As you may or may not be aware, Drools 3 will have a non XML language for
DRL.
Drools 3 uses the normal pattern of a content based AST representing the
language constructs as parsed out of the source. (these classes currrently
have the Descr post-fix to indicate they are description classes).
Now, some there still is a requirement to support XML (but not require it) -
for people who are generating rules form other systems, or who need to
interchange etc. Also, a "native" XML format would serve as a useful
foundation for doing XSLT from various flavours of RuleML, OWL etc etc..
(and whatever else).
I have created a JIRA to track this
http://jira.jboss.com/jira/browse/JBRULES-61
I am interested in input in anyone with a fair bit of experience with good
XML binding tools. My experience is a little old, and is with JAXB 1, which
I would defintately *not* recommend unless you like pain these days.
We want to do a 1 to 1 binding from XML to the Descr classes,
http://anonsvn.labs.jboss.com/trunk/labs/jbossrules/drools-compiler/src/main/java/org/drools/lang/descr/with
PackageDescr at the "top" of the tree. I guess we will need an XSD, or
perhaps generate one from the Descr classes (as they will be "the source of
truth").
Anyone have ideas or want to get involved?
