Parser torture documents

[Chris Nokleberg <chris@sixlegs.com>]

I'm looking for xml documents that will really stress a parser, in
particular a SAX2-compliant parser. I searched the archives and found
a reference to "CMSMQ's Torture doc", but I can't even figure out what
CMSMQ is.

Some things that would be nice to test are:
  large DTDs (many elements, default attribute values)
  many non-ascii characters
  many entity references/PEs

Thanks!
