RDF Site Summary 1.0 Modules: mod_enclosure

Hello,

By validating my RSS 1.0 with the validator.w3.org validator I get the 
following error "Use of unknown namespace: 
http://purl.oclc.org/net/rss_2.0/enc#". Yet it is indeed a valid and 
quite common namespace.

*xmlns:enc="http://purl.oclc.org/net/rss_2.0/enc#"*

Tx.
