Ah, yes, nice, I did not see it. I did not look yet in the informative
appendices. It is no problem of course to add this, to check 
documents.

For them if found the doctypes and use them since years. I think, when 
I tried, I had only a problem with the SVG basic 1.1 doctype provided 
in the mobile recommendation - the validator did not like it. But the 
basic variant is discontinued anyway...

I do not have an account (yet), but if no one else with an 
account is interested, I can create one ...

Yes. It helps a lot to have a reasonable check, especially if one writes
tests - one is often surprised about the results and is always looking, 
if it is only an error in the expectations, in the document, in the viewers 
or something more serious ;o)
This remains a problem, but I did not look around, if there is a program
able at least to check a document with this RelaxNG. 
However, the more tricky things one has to test are only in the prose
of the recommendation anyway.
