No, it is not a syntax solution.  It changes values such as "illustrator", 
"choreographer" or "producer" from being *sub-elements* to being *data*.

I'm uncomfortable with your use of the word "qualifiers".  At DC4, we used 
this word to mean one of:

   1.  language
   2.  scheme
   3.  type (sub-element name)

See http://www.dlib.org/dlib/june97/metadata/06weibel.html for the DC4 
report.

In my proposal, "choreographer" moves from being a qualifier to being a 
member of a vocabulary, just like "Ming Dynasty" in:

   <meta name="DC.coverage.periodName" scheme="historic" content="Ming Dynasty">

Indeed, it is generally helpful if a group of people agree on a 
vocabulary.  We will, of course, have hundreds of vocalularies, adopted by 
various groups for specialised uses.  Some vocabularies will emerge as 
having more general use.

That's where RDF comes in, I hope!  HTML's META element syntax doesn't 
support grouped, repeatable elements.  We'll be given lots of info on RDF 
at DC5.
