..which means, if your parser is not a validating parser, what you receive
and can do will vary.  We have a "grayness" between well-formed and
validating that doesn't sit too well.

Absolutely.  We need well defined classes of parsers so that implementors
and users can require a certain level of processing.  We also need 
conformance test suites for these each class of parser.

Currently, validating parsers are the only real *safe* bet.
