You might pass a validation test (although I don't see a relation between
CSS validation and the statements above) but you loose browser
compatibility. Some major browser expect the DTD to be the FIRST line in
XHTML code or they will render the document in quirks mode. This small
little difference results in different visible font sizes etc.

IMHO the problem is the line <?...?>. This line is even optional in XML and
not required in XHTML. It should be only used if you are using another
encoding than the defaul XML encoding, which is UTF-8.
