Do you have any examples? Our aim is to improve Relaxed in future and to 
add support for compound documents with elements from several 
namespaces. Something which can be hardly managed by DTD based validation.

User will get this information when HTML page is validated and he/she is 
also suggested to double check it with SGML based parser.

But you are right that name XHTML validator would be less confusing.

There are much more things. E.g. compare:

http://validator.w3.org/check?uri=http%3A%2F%2Fkosek.cz%2Ftemp%2Fdemo01.html

http://badame.vse.cz/validator/validate?validator_url_parameter=http%3A%2F%2Fkosek.cz%2Ftemp%2Fdemo01.html&validator_option_parameter=xhtml&validator_process_button_parameter=Validate

The sample page doesn't conform to XHTML specification in at least 4 
aspects. They are catched by Relaxed, but silently ignored by DTD based 
W3C validator.

Dirty parser option always preprocess input with TagSoup.
