Without stirring up a hornets nest here....  First, let me say that I am 
solely responsible for the contents of the draft.  If there are 
editorial errors, they are mine alone.

It is my understanding that extending the content model of link and meta 
is essential to permitting the types of annotation that you all wanted.  
Certainly it is possible that the RDFa minimal content model in this 
module, which is an XHTML Modularizaiton 1.x module, NOT a 2.x module, 
can be whatever you all think is reasonable.  I don't care.

With regard to the predefined values... I guess we need to clarify what 
you are concerned about. 

First, this is the XHTML namespace, not the XHTML 2 namespace.  (There 
is no longer an XHTML 2 namespace.)

Second, the values of @rel for example, are the ones that we need to 
preserve from M12N 1 + some that the working group decided to add. 

Third, the values for @property are ones that the working group 
identified as important values for extending the property mapping model 
to deal with shortcomings in the longdesc attribute, the title 
attribute, and some other places.  In addition, since @property is meant 
to replace @name, values that are commonly used in @name (unprefixed) 
needed to be included in the set defined to be in the XHTML 1 namespace.

I hope this clarifies some of the issues you have raised.  I look 
forward to continued discussion and evolution of the draft document.  If 
anyone wants to assist in editing - I am totally open to that!
