[antlr-interest] AST cardinality from called rules

Hello list,
The following rule generates the AST that I want:
localVariableDeclaration
: LOCAL variableDcl ( ',' variableDcl )* -> ^(LOCAL variableDcl)+
;
But how do I generate an equivalent AST if the variableDcl list is not
in the localVariableDeclaration rule, as in the following fragment?
localVariableDeclaration
: LOCAL variableDeclarationList
;
variableDeclarationList
: variableDcl ( ',' variableDcl )*
;
I want to produce a set of ^(LOCAL variableDcl) subtrees, but I want
to reuse the variableDeclarationList from other rules, so I'd rather
not inline it.
Thanks!
