As I said in the original comment, it's clear for attributeType="XML",
it's not clear for attributeType="CSS". Another simple case where this
is different is "scientific notation", it would be allowed when the
target is an XML attribute, but not when the target is a CSS property,
since a value like "1e3" is not a legal property value even though it
would be a legal attribute value. Whether comments and such are allowed
in the presentation attributes isn't clear from the draft, as has been
discussed many times on this list.
