Hi Michael,

Most elements are defined as EMPTY in their module DTDs.  
These are just simple default values which  are used to keep the module DTDs
independent from one another.  The actual content model of elements like
layout depends on the profile that is in use.  For the SMIL language profile
this is defined in the file smil-model-1.mod.  There the content model
of layout is defined as:

<!ENTITY % layout.content "(region|viewport|root-layout|regPoint)*">

The SMIL Basic profile's layout content model, however, is defined 
in smilbasic-model-1.mod as:

<!ENTITY % layout.content "(root-layout?,(region)*)">

Hope this helps,
