Basic Documents]


The most straight forward way to declare that a document can be played by a
smil basic player is:

<smil xmlns="http://www.w3.org/2001/SMIL20/WD/Language" 
	xmlns:basic="http://www.w3.org/2001/SMIL20/WD/HostLanguage" 
	systemRequired="basic">
...
</smil>

Host language conformance is the mininum set of modules that a conformant
smil basic user agent is allowed to implement.

We expect that other standards bodies will build profiles starting with the
smil basic scalability framework and the host language conformance set.
These profiles can have their own doctype/namespace/dtd and make documents
written in them directly identifiable as such.
