[imsc] Definition of prohibited does not prohibit presence of feature.

skynavga has just created a new issue for https://github.com/w3c/imsc:

== Definition of prohibited does not prohibit presence of feature. ==
Section 4 states:

shall not use any vocabulary, syntax or attribute values that would 
require the processor to implement any "prohibited" features to 
successfully process the document.

If the intention of this language is to prohibit the presence of a 
feature, e.g., use of <p> in the image profile, then this language 
does not accomplish that goal. In particular, it permits an 
interpretation that a prohibited feature may be used even though it 
does not require the processor to implement support.

In other words, the term *prohibited* does not mean that a feature not
 be used. It only means that the author of the document cannot use 
<feature value='required'> for a prohibited feature.
