Consider it obsolete. It's an old document lying around, with no 
authorship or status information. Did you notice its title?
<title>HTML 4.0 Specification</title>
(A poor title indeed, but it happens to indicate that the document 
was somehow related to HTML 4.0, which was obsoleted in 1999 when HTML 
4.01 was defined. It wasn't part of HTML 4.0 specification, though. Just 
someone's notes.)

Besides being in a document with no status, this would not affect the job 
of a validator the least. It's a restriction specified in prose, not in a 
DTD.

It's not meant to. The values of rel and rev attributes are declared as 
having type CDATA, which means any string - "anything goes".
