[imsc] Pull Request: Proposed updates re foreign namespace content

nigelmegitt has just submitted a new pull request for https://github.com/w3c/imsc:

== Proposed updates re foreign namespace content ==
* Clarify that foreign namespace attributes are permitted on all other
TTML1 elements not just Content elements.
* Add an informative note:

> For validation purposes it is good practice to define and use a
content specification for all foreign namespace elements and attributes
used within a Document Instance.

Half-apologies that my editor (Atom) has taken it upon itself to remove
trailing whitespace from all lines in the  document.
