Talking about the general case, as opposed to RDFa in particular, I'm not 
convinced that is the right criterion for deciding there are no issues with 
respect to media type registration. First of all, at the very least, it 
needs to be shown that none of the fragment syntax that the new facility 
defines for non-anchor references overlaps with syntax already devoted to 
identification of anchors.

Furthermore, even if there were no such conflict, the position you take 
seems to violate the spirit of the Self-describing Web finding [1], which 
says that when new formats are needed for use with the Web: "it's essential 
that the pertinent specifications be reachable by references, preferably in 
the form of Web links, from the specifications for existing Web 
technologies." Returning to the example of RDFa in HTML in particular, the 
chain of specifications that cover the interpretation of representations of 
format text/html runs through the media type registration.  Therefore, it 
seems to me that even if any new fragment syntax is used for purposes 
completely unrelated to identify portions of the representation, it is 
still essential that the specifications for interpretation of the new 
syntax be reachable following a normative chain through the media type 
registration.  What am I missing?

Thank you.

Noah
