Re: Please clarify: XHTML 1.0 Strict allows relative base URIs

Some points in your questions are clear:
- RFC 2396 was obsoleted by STD 68 some years ago, but the W3C
  didn't bother to update the XHTML 1 standard and DTDs so far.
- DTDs cannot formally express a datatype for URIs in attribute
  values, let alone for absolute URIs, at best you get a hint
  where to find the specification (e.g., *NOT* in the obsolete 
  RFC 2396, or *NOT* in the obsolete RFC 3066, etc.) in the
  form of a DTD comment.
- XHTML 1 is designed to approximate HTML 4 as far as possible
  down to stuff like "NMTOKEN can't be an empty lang=''".  It
  is arguably not the job of XHTML 1 to fix such HTML 4 issues.
