To me the document is fine the way it is, save for the "optional"
part.<br>
The text <br>
<br>
NOTES: Although not yet reflected in this document, the notion of
"optional"<br>
refers to an attribute whose inclusion is deemed to be optional according to<br>
this specification. Likewise, some attributes are required. A future version<br>
of this document will make the "optional" versus "required"
distinction<br>
clear, for both tags and their attributes.<br>
<br>
As a matter of philosophy I object to the use of the term "optional"
in a<br>
standard, because the purpose of a standard is to tell users what they<br>
should do to achieve interoperability.<br>
Of course I know that not everybody may have the same notion or requirement<br>
of interoperability. As you may remember from an earlier post, since its<br>
early days MPEG has struggled with this reality and has come up with the<br>
"profile and level" approach. <br>
Instead of having a placeholder for "optional" with the intention to
give it<br>
a meaning later, I would like to give a meaning to "optional" and
then find<br>
a place for it.<br>
As I said interoperability requirements are not the same for all, so there<br>
is nothing new for MPEG in your request, but I would like to get a<br>
formalisation of the thing before admitting it in<br>
