Tricky one.  If detected, it should be a fatal error in the draconian
XML style.

Wow... what would they actually do, I wonder?  This seems kind of horrid.
I think it should stay fatal, on the following analogy: if a document
contained "<foo<<<<>" and a broken system I/O library supressed all but
the first "<<<<<", the error would be undetectable.  But the document's
still broken.  I think the analogy is exact. -T.
