Hi Mark,

Throughout this debate you have kept sayiing that RDFa is not intended 
originally to be an RDF serialization. Is 
http://www.w3.org/2001/sw/BestPractices/HTML/2004-10-12-charter the most 
up-to-date charter for the task force? If so, I am confused by your 
contention, as the charter's mission statement says:

"""
The task of the RDF in XHTML Taskforce is to:

    * State requirements for representing metadata in RDF within an XHTML 
document
    * Evaluate proposed solutions against those requirements.
    * Recommend to the HTML WG and the SWBPD WG how to proceed to achieve 
a common, widely accepted way of representing RDF metadata within an XHMTL 
document.
"""

...which, to me at least, pretty clearly says that the taskforce's goal is 
to serialize RDF metadata within XHTML. Note that the mission does not say 
something to the effect of: "state requirements for interpreting the 
semantics of XHTML documents", which seems to be your primary concern, if 
I understand your repeated statements correctly.

In any case, count me in among the community members who find RDFa much 
less useful if the default serialization is XMLLiterals. My personal use 
cases for this space involve serializing RDF within (X)HTML, and while I 
would prefer a W3C-endorsed solution, I would prefer a non-W3C solution 
(eRDF) over a (to me) cumbersome W3C solution (RDFa with XMLLiteral as the 
default).
