It does seem to me, though, that it might be useful if W3C Recommendations
flagged any potential legal / copyright issues which implementations of  
the recommendation may encounter.  This was brought home to me at a
SMIL Tutorial at WWW10.  The feature in SMIL to  integrate various
resources, and to, for example, start a video clip at any arbitrary 
point looks like it will provide copyright lawyers with a nice income
stream ("I'll start the Disney video clip after the copyright statement 
has finished, and I'll add my own logo at the top of the window").
