Oh, right. You didn't say that before :) The default now is to
assume ANTLR v3 unless otherwise specified, and you can't do that
in v3.

When you have a tree parser in a separate file like this, you need
to specify the importVocab option, so that it knows how to find
the token definitions.
// in the parser
options {
exportVocab = XHTML;
}
// in the tree parser
options {
importVocab = XHTML;
}
