The page now uses XHTML 1.0 Strict and validates fine with both

I would guess that what happened previously was that the page used a
custom XML DTD, which can lead to validation errors if the validator 
assumes that the DTD is SGML rather than XML.  Likely the two validators 
have different heuristics for deciding which of SGML or XML to assume.

For validating a custom XML DTD with the WDG HTML Validator, see
