Sure there is. The "href" attribute to the "A" elementis defined to be
"%URI" which is in turn defined to be "CDATA": "a sequence of characters
from the document character set" that "may include character entities".
That is one check that can, and should, be made. If it passed the HTML you
passed it, it's a bug and should be fixed.

(
    In addition, there is no reason why we can't add additional checks to
    make sure that the document follows the Recommendation and not just the
    DTD. The Validator isn't supposed to just Pretty Print the output of
    SP, it's supposed to check the document for actual Validity. How
    feasible that is in practice is another matter and each extra check
    needs to be examined carefully before implemented. Maybe the check
    should be foisted on Weblint or be made an optional feature not
    directly related to the validation pass.

However, "g:foo" is perfectly valid. Just because it isn't a recognized
scheme, doesn't make the syntax invalid. This is a XML/SGML validator; not
a URI validator.
