Hello SMIL working group,

some comments on chapter 10


'The smil element can have the following attributes:
The id attribute uniquely identifies an element within a document. 
Its value is an XML identifier. ...'
 (this and other attributes defined here)

-> only the smil element or an element within a document?
any element?

-> what about xml:id, is there a plan to introduce this
more general identifier in SMIL? This seems to be
useful, especially for SMIL, combined often with
other XML host languages...

-> it is maybe useful to combine attributes usable on
all elements with a shortcut and to reference these
common attributes in the element specification.
This could be done similar to the HTML4 recommendation
for example, where all applicable attributes are listed
for each element in the element definition and 
referenced if not defined with the element itself.

-> it is a little bit confusing that some attributes
are defined here (only) for the smil element, but
used in examples or in some profiles for other
elements too. For a 'naive' reader it is not quite
clear, how this really works, because it is not
explained (here).


'The smil element can contain the following elements:

-> an arbitrary number of head and body elements
or exactly one head and one body or a maximum of
one head and one body?
