[rules-dev] Enhancements to Rule XML (BRL)

[Mark Proctor]

  In reality I'd like to see the BRL killed. We already have two poorly 
maintained xml formats, neither keep up to date with DRL.

BRL was initially designed as a simple xml, as we believed tooling 
wouldn't want full DRL. As it turns out most people do actually just 
want a GUI builder that supports full DRL.

As a result I'd like to see an investment in a new XML format that 
future proofs, for our designs for drools 6:
http://community.jboss.org/wiki/DroolsLanguageEnhancements

I've been reluctant to start my own XML here, as i'd like to see us work 
with the RuleML group in adopting their xml (probably with feedback on 
needed changes) as our defualt XML for Drools.  Although for the 
immediate need for improving the guided editor we have no choice but to 
continue to extend BRL, but those doing so should probably have it in 
mind that it's a temporary solution.
