Debatable indeed, and my opinion is that everything should be elements.
For consistency. :-)

Sure, use the validator (and I'm assuming here that is designed as a
JavaBean that can be used in more ways than just commandline. Anything
else would be a major mistake).

No, I want to use the validator as all rules are not suitable for a XML
parser to check.

As above, a validating parser can't handle the heat. The rules are too
complex. And every vendor could use the same validator. .. oh.. here
comes an obvious one:
REUSE
;-)
(BTW, try running the example through the Project X parser...)

If that rogue editor is bad, don't use it. 8-)
This is an important discussion! More comments!!
