in addition to Jirka's comments, you pretty much have to use a catalog
or some such anyway (in which case the about: URI is as resolvable as an
http one).

Even for DTD that are apparently resolvable such as

http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd

If you actually GET that URI more than a few times the W3C will cut you off
with a 503  code, to prevent their servers being overloaded

http://www.w3.org/blog/systeam/2008/02/08/w3c_s_excessive_dtd_traffic

So the difference between an about: URI scheme and an http: one is not
as great as may seem.
