[rules-dev] Declared types - extension

What's the rules around declared types extending another (declared) type?

I've been asked to provide for declared type extension in Guvnor (by
Prakash) but the Expert user-guide doesn't say it exists at the engine
level.

I tried "declare MyType extends java.util.ArrayList" and received a
parser\compiler error stating "java.util.ArrayList was not a declared type"
(or words to that effect) so some form of extension appears possible.

Thanks,

Mike
