Invalid namespace URI

Hi All,

We have found another corner case while looking at all the wonderful 
RDFa on the Web:

The page at [1] contains:


This
work by <a
xmlns:cc="http://creativecommons.org/ns
#
"

which is probably not intended (the page is broken in some sense). When run through either the XSLT or the Distiller this
becomes:

      <cc:attributionName xmlns:cc="http://creativecommons.org/ns #">New Jersey State Auto
Auction</cc:attributionName>

which is normalized [1] as 

xmlns:cc="http://creativecommons.org/ns&#x20 <http://creativecommons.org/ns&#x20>;#">

It seems to me that what you get is XML well-formed but not namespace-well-formed [2] because the attribute value is not a valid URI.

Not sure really what to do about this but the output is not very 
useful... should the tools raise some warning?

Thanks,
Peter
