[ttml2] Allow initial style to be constrained to an element type? (#1234)

nigelmegitt has just created a new issue for https://github.com/w3c/ttml2:

== Allow initial style to be constrained to an element type? ==
Whereas some style attributes, such as `tts:backgroundColor` apply to multiple types of element, e.g. `region`, `div`, `p` etc, only one value of any style may be specified in the `initial` element. This means it is not possible, say, to set the initial value for `tts:backgroundColor` only as applied to `span` elements. 

Would others find it useful to be able to specify this semantic?
