[VE][47] HTML 4.01 Documents can not be validated

Error [47]: "end of document in prolog"

HTML 4.01 documents that have been validated as correct can not be 
validated any more due to the above error. 

I am in charge of a website (http://publik.tuwien.ac.at/start.php) 
whose pages I regularly validate using the validation feature of 
Opera. Until very recently, the pages were found to be correct HTML 
4.01; currently, the validator stops with the above error message. 
Since I am neither aware that HTML 4.01 has recently undergone 
changes in its specifications that might have turned previously valid 
pages into invalid ones, I suspect that there is a bug in the 
validator (which apparently expects items now that previously were 
not in the HTML 4.01 standard).

Thank you for any clarification!

Cheers,
Karl Riedling
