RE: <use> remote CC licence

At least, the SVG always contains the complete URI of the referenced 
fragments and the viewer has to get the complete document to extract
the fragment. Therefore the author of the referencing document cannot
really hide the fact, from where the fractions are extracted and anyone
can follow the references to see the complete original document 
including licence conditions, if there are some.
I think, in some or many countries it is not even necessary for the
author to add specific licence conditions, already the absence of
any conditions is a general protection of the document if it is complex
enough. This is for example the case with the german 'Urheberrecht',
therefore typically for german authors it is not necessary to add 
any information about copyrights or something like this, if they do
not want that others republish their work. 
For example, a reuse with the use element from one of my SVG
documents and republication would be illegal by default if I note
nothing different in the document.

I think, it will be difficult for viewers to analyse information in the
metadata automatically, even if this is RDF, to determine, whether
the extraction of fragments is legal or not.
The technical requirement for SVG would be for example to
specify that viewers must be able to interprete RDF and maybe some 
other formats and must be able to interprete licence documents
somehow - are there formats or extensions to determine licence
conditions automatically or even to note them in an international,
language and country independent format? As you can see above, 
even the absence of metadata already means some very restrictive 
conditions as the simplest case, but what about more complex cases?
