The RDFa syntax spec has a blockquote example,
http://www.w3.org/MarkUp/2010/ED-rdfa-syntax-20100113/#sec_6.3.2.1. 

If we rewrite it a little, it looks like this:
<blockquote id="q1" about="#q1" rel="cite" 
resource="urn:ISBN:0140449132" >

and generates
doc#q1 <http://www.w3.org/1999/xhtml/vocab#cite> <urn:ISBN:0140449132>

And I think that this:
<blockquote id="q1" cite="urn:ISBN:0140449132" >

should generate the same triples. 

So, perhaps one of the first things that should be done would be to add 
@longdesc to the XHTML vocab profile so that one do the same for 
@longdesc.
