Yes, this will be my first line of attack! Looks like you've solved 
most, probably all, of the problems already.
As for playing around with Antlr, I had the crazy idea of describing 
the output XML in the actual grammar, either by extending the grammar 
vocabulary (the grammar grammar!) with XML output directives, or by 
parsing the grammar to XML format, manually include output nodes in 
this grammar, then transform it back into Antlr format plus XML 
generating code. Or something like that.
With the grammar in XML format, it's easy to write tools that eg 
eliminate left recursion (see YAPP on the o-xml web site).
Anyhow... too many crazy ideas, too little time in the day!

Thanks for the mail, and thanks for the work you've done on SrcML - 
it'll make my life easier!

regards,
