right, but -as opposed to a dc:language property - it has no effect on
the Image resource but only on the plain-literals within it, given that
link is a plain-literal (but it should be XSD anyURI) the language
information applies also to this one, which seems a bit strange to me.

I don't think having separate RSS feeds with different URLs is a good
idea when using a protocol which supports language negotiation [1]. For
a page that supports multiple languages bot statement:

<http://wymiwyg.org/> <rss:title> "Willkommen bei wymiwyg"@de
<http://wymiwyg.org/> <rss:title> "Benvenuti da wymiwyg"@it

seem to be equally correct. In both stmts "rss:title" refers to the
primary title and so using a different property (like dc:title) does not
seem to justified. While for RDF-Applications I see no reason for
limiting the title to one - this may be reasonable for XML-Clients (I
don't know, I don't do XML), if this is the case it should be
constrained in the XML Schema - not in the ontology. This would allow
both of the above statements to be in the rdf-repository on the server,
but when a RSS document is delivered the title that best matches the
client's request is delivered.
