I originally started with "context/dc:title", but added more magic by 
making the namespaces map to a ZPT expression type (so it could be 
done). But this is probably silly since you then have to make sure so 
twonk tries to to map XPATH to the 'path' prefix... Although 
tal:content="dc:title" looks nicer... so I'm confused.

One issue I just thought of - how does this map to METAL? If we allow 
the 'namespace prefixes' to be changed
in the TAL, this could change the interpretation of the macro so that 
instead of the Dublin Core title being
rendered, some other bit of metadata called title is. Is this a feature?
