In actual fact, if I'm reading the wiki page right (and it's only 
briefly mentioned in one sentence, so could be wrong), actions can 
be defined on a target-specific basis.  So probably all that needs 
to get done is that *above* the <ruleInitializations()> line, add 
a new line with <ruleDescriptor.actions.decls> or similar.  Then 
you should be able to declare local variables in a @decls block 
rather than the @init block.
