DTD traffic has to be the single most expensive and problematic issue  
in terms of w3c infrastructure, and w3c as a whole (incl the TAG) has  
been promoting the use of caching and cataloguing to alleviate that  
situation. As a result, I am reluctant to have the markup validator  
fetch a DTD (or, in the case of modular specs, a dozen) every time a  
validation request is made (that's a couple million times a day, IIRC).

Are these DTDs changing so often that it would be a burden for the  
XHTML WG to drop a mail to www-validator saying "the DTD for foo has  
been updated, please update your catalogs"? Remember, readers on this  
list include not just developers for the W3C's validator, but pretty  
much all of them.

That said, if a DTD is changing a lot for a period of time, we could  
remove it temporarily, upon your request, from the validator's  
catalog, but that should not be systematic.

Thank you for the info. When is the PER expected to be published?
