But the fact that the "same item" can have so many different lexical
forms means that getting the right answer every time necessitates
parsing the XML.

All forms of accurate XML data processing - even the dumbest
lexical processing - involve parsing of some form. The idea
that 
	non-parsed <-->  parsed
are two ends of an extreme with clear blue water in
between does not seem right to me.
