Olaf,

it's possible to use a script to display cc metadata: http://www.openicon.org/feeds/zanadu.svg
if one considers a collage like Sgt Pepper's Lonely Hearts Club Band  
LP Sleeve, or
http://www.openicon.org/db/on-sets/index.svg, where there are many  
icons from different resources
this can become overly complex.

perhaps the SVGWG can consider how <use> remote might be combined with  
script, or the UA or AT to display CC metadata if required?

the purpose of CC is to ensure that end users can immediately and  
easily understand their rights.
especially in the case where these automatically allow some reuse.

It is also true that I had raised an enhancement bug with nathan  
yergler around 2002 to implement mozcc for svg, but it appears there  
are significant obstacles.

regards
