Re: revised description of RELAXED feature

Alek,

I think we actually need two properties or some kind of leveling:

0: parser strictly rejects malformed XML

1: parser accepts well-formed XML, but also may accept some malformed 
XML (some well-formedness checks are not implemented)

2: parser tries to make its best effort to read anything. This is needed 
for real-world HTML parsing or the implementation of tools similar to 
HTML-Tidy.

kXML can operate in modes 1 and 2.
