(I am using a strict XHTML 1.1 drupal theme.)

There are some w3c validation issues with RDF information in
->the creative commons site licence block
->the creative commons node licence block

(even when unchecking "Insert RDF/XML" in the creative commons module configuration)

See the w3c validator output

Line 261, Column 12: there is no attribute "about"
<div about="http://URL" instanceof="cc:Work"

 Line 261, Column 63: there is no attribute "instanceof"
<div about="http://URL" instanceof="cc:Work"

 Line 265, Column 349: there is no attribute "rel"
… neighboring rights to this <span rel="dc:type" href="http://purl.org/dc/dcmit…

 Line 265, Column 364: there is no attribute "href"
…ghts to this <span rel="dc:type" href="http://purl.org/dc/dcmitype/">Work</spa…

 Line 265, Column 423: there is no attribute "property"

Thanks for this great module,

It's the ccREL metadata that's causing these validation errors. I've tried to follow the ccREL specs best I could, but I think the issue is that it relies on elements outside of the XHTML namespace.

There are two xmlns attributes specified: xmlns:cc="http://creativecommons.org/ns#" and xmlns:dc="http://purl.org/dc/elements/1.1/"

They could be specified in the wrong place, though in trying to manually place them beside the XHTML xmlns specification up in the main element, I was still seeing validation errors. Either we've got them in the wrong place, or ccREL can't validate against XHTML.

The "Insert RDF/XML" flag only actually turns off the old metadata, which was RDF/XML including inside of an XHTML comment. The ccREL metadata is always on in the module, embedded in the license description.

Should there be a setting to turn off metadata entirely? Or is there a way to include additional namespaces and allow it to validate? Might need to ask some folks at CC...
