Kepping out of the disscussion whether we need the 
transitional DTD anymore, there were both transitional and a frameset
DTDs because:

  The content model for HTML documents depends on whether the HEAD is
  followed by a FRAMESET or BODY element. The widespread omission of
  the BODY start tag makes it impractical to define the content model
  without the use of a marked section.

from http://www.w3.org/TR/REC-html40/sgml/loosedtd.html

The problem with 
is that this makes it invalid to ommit the BODY start tag 
in non-frameset documents.

In XHTML this is not an issue, since all start and end tags are required,
so the transitional and frameset can be made into one DTD.
