Document validation is perhaps the wrong layer to check what are
actually relationships between documents.

I'd suggest links of all sorts - a@href, img@src, blockquote@cite,
img@longdesc, etc. - are best checked with a link checker:

http://validator.w3.org/checklink

It would additionally be good if link checking was incorporated into
total validation tools such as:

http://validator.w3.org/unicorn/
