[rules-users] Efficiency questions about DSL

[Michael Anstis]

It's a deliberate decision in the workbench; as it follows what is
supported by the core engine.

I've asked the core engine developers to comment on whether the underlying
Drools engine supports (does support, should support or will support)
cross-JAR DSLs.

With kind regards,

Mike
