JCD: I understand your preference for "flexible type" languages, but we 
have to deal with Java/C/C++/... as well.

JCD: the load event is for when the media element doing the loading is 
"installed" into the scene tree. That is very different from the time 
when the loading of the resource is finished. This could happen when 
xlink:href is modified dynamically, well after load has been sent for 
the media element. Or did I misunderstand you ?
