Really great to see this back online!

A question about URIs, RDFa, conneg, http-range-14 etc:

(sorry!)

"""          <div id="conceptDetailTab" 
about="http://id.loc.gov/authorities/sh98002696#concept" 
typeof="skos:Concept">
                 <h1 property="skos:prefLabel" xml:lang="en">Bristol 
Bridge Massacre, Bristol, England, 1793</h1>

                 <span rel="skos:inScheme" 
resource="http://id.loc.gov/authorities#conceptScheme"/>
                 <div id="concept">
                     <br/>

                     <b>URI:</b>
 
&lt;http://id.loc.gov/authorities/sh98002696#concept&gt;
                     <br /><br />
"""

If http://id.loc.gov/authorities/sh98002696#concept is the URI of the 
skos Concept, aren't we supposed to avoid using it in the HTML markup 
when an XHTML/RDFa representation is made available? ie I remember from 
a previous thread that (against many intuitions) id="concept" should be 
avoided. Otherwise we get into that boring thread about whether it is a 
URI for a piece of HTML or for the thing the HTML describes / represents...

Sorry to nitpic, but I guess this is why W3C does implementation surveys...
