If you assumed > @rel in HTML or XHTML was a URI, you went beyond the spec. Again, the assumption, if any, is that the @rel value alone identifies the relation.

Where does the spec say that?

And that's what is incorrect. *Because* the syntax is a plain string it's an incompatible change to define a new syntax here. Keep in mind that "foo:bar" already was a syntactically legal relation value before. Best regards, JulianReceived on Thursday, 5 March 2009 12:10:36 UTC
