Yes, that is similar to a switch, somehow a little bit simpler and a little 
bit less flexible. Sometimes maybe the size or the default 'noise-level' 
of the  video may change with a different format, this may cause some 
minor problems, for example how to set width and height and for 
alternative formats?

Interesting, that the source behaviour is described in the draft before the
source element itself is defined - maybe a hint for a bad document structure,
not sure about it.
If it is intended, that 'normal' readers can understand the draft, I think 
it is important to have a good document structure (I had already a similar
discussion about the current SMIL draft ;o) - but this is sometimes not a
really easy task.
