[antlr-interest] CSharp3 language not generating heterogeneous nodes

[Sam Harwell]

Since the hetero-node feature was infrequently used compared to certain
rewrite situations, the C# port of ANTLR uses a different syntax for hetero
nodes.

The new feature is explained in section 5.8 of the documentation on the
following page:
http://www.antlr.org/wiki/display/ANTLR3/Antlr3CSharpReleases

To use the hetero-nodes, you'll need to use the full syntax. Instead of
this:

Token<NodeType>

You'll need to use this:

Token<node=NodeType>

Subject: [antlr-interest] CSharp3 language not generating heterogeneous
nodes

I want to generate an AST using heterogeneous nodes using the C# 3 language.
My grammar uses rewrite rules.  Unfortunately, it doesn't look like the
generated code utilizes my specified custom node types at all; rather, only
the ASTLabelType directive is respected. Is this a known limitation of the
CSharp3 target, or is there something additional I have to do besides
specifying node types in the rewrite rules?
