[rules-users] problem in DRL to XML conversion

[Edson Tirelli]

   Niloy,

   I think there maybe a confusion here. You can create the full descriptor
tree without any problems, since that's what the parser does. Just create
the AND tree for the LHS and set it to your RuleDescr and after that add it
to the PackageDescr.

   When in doubt, look at what the parser does. Here you can see the ANTLR
grammar for DRL files:

   Hope it helps.
