As you say URL's can point to anything. Why then explicitly type them by
calling them VideoURL etc? The only reason I can think of is to give the
user some idea of what's behind the URL, but these attribute names only 
indicate the type, not a content of any sort. And the type maybe 
negotiable through HTTP or whatever anyway.

Would it not be more flexible and descriptive to have a one-liner of 
HTML in there? E.g.

Name: URL
Value: <A HREF="http://whereever/earth.html">A Picture of Earth</A>

Or even simply 

Value: <url><space><description>

where the description is optional.
