[Imps] Liberal XML parsing

[Sam Ruby]

I've posted a note on how the code in html5lib could serve as an 
excellent foundation for a number of "liberal" XML parsing tasks:

Personally, I'm not overly interested in hearing more opinions as to 
whether or not there is a valid demand for liberal XML parsing.  If you 
don't want to use it, don't.

What I WOULD be interested in hearing opinions on is what would be the 
best way to maintain this code going forward: could it live as a 
separate module within html5lib repository?  Should it be a separate 
repository?  If separate, are there some changes to the tokenizer in 
particular that could be made that would either directly enable this 
usage or would make it easier to monkey-patch for usage by xhtml5lib?
