    I guess the question is how much RDF parsing do you have to
do to figure out if there is CC data or a part description or credit
card info or anything else that anyone can imagine putting in the
metadata tag of SVG.  Or perhaps CC data embeded in a credit card
charge embedded in a Bill of lading etc.

    My feeling is that if someone wants copyright information
at the top of view source they should put copyright information at
the top of the source! Is this really such a hard idea to grasp!

    I'm not so sure it is likely to really be such a small step.

    What I think is being asked for in a very roundabout manner is
a 'bozo bit'.  A simple yes/no flag in the content that says 'allow
save'/'don't allow save'.  This could be a simple attribute (perhaps
two, one for view and  one for save ) on the root SVG element and the
SVG  specification could require User agents to respond to them
(similar to how they are required to defeature in the face of 
panZoom="disable").

    If this is what people want please don't force implementors to
muck with the contents of metadata tags and all of RDF.  Let
the author express the intent directly to the UA.  Then if authors
want to put in the RDF they can but UA's can continue to blithely
ignore everything under a metadata tag as the Specification currently
suggests.
