Not fully useful 'name' attribute type of 'meta' element.

Hi, take a look at this:
http://www.w3.org/TR/2001/REC-xhtml-modularization-20010410/abstract_modules.html#s_metamodule

Could @name attribute type be changed from NMTOKEN to NMTOKENS i next  
revisions?

This would allow us to do such things:

<meta name="dc.description description" content="foo" />
<meta name="dc.subject keywords" content="foo bar" />
<meta name="dc.creator dc.rightsHolder author" content="John Smith" />

Right now (while waiting for XHTML2 and RDFa) web authors are forced to  
duplicate content in documents.
This could be very useful and also I do not see any drawbacks of such  
change, so maby this could be moderately quickly done?
