| This is a kludgy hack that assumes that Dublin Core has exculsive use 
| of <link rel="schema.DC" /> and <meta name="DC.*" />. 

See section, 2.6 of the article linked above. 'DC' is an arbitrary 
string. The following are to be considered equivalent:

<link rel="schema.DC" href="http://purl.org/dc/elements/1.1/" />
<meta name="DC.date" content="2000-01-01" />

				-and-

<link rel="schema.DUBLIN" href="http://purl.org/dc/elements/1.1/" />
<meta name="DUBLIN.date" content="2000-01-01" />

				-and-

<link rel="schema.FLIBBLE" href="http://purl.org/dc/elements/1.1/" />
<meta name="FLIBBLE.date" content="2000-01-01" />

The 'DC' in 'DC.date' (or the 'FLIBBLE' in the third example) is just a 
reference to the URI with rel 'schema.DC' (or 'schema.FLIBBLE') -- like 
an ID/IDREF pair in XML -- the actual ID used is irrelevent (although it 
is probably sensible to use a mnemonic one such as 'DC' or 'DUBLIN') as 
long as it is applied consistantly.
