ISSUE-389 (Embedded graphics requirement): Embedded graphics don't fully meet requirement [TTML2]

http://www.w3.org/AudioVideo/TT/tracker/issues/389

Raised by: Nigel Megitt
On product: TTML2

Requirement R217 - Embedded Graphics is:

> The TT AF shall be capable of expressing block and inline, embedded graphics of both bitmap and vector or outline formats.
>
> If block or inline graphics are used for the purpose of expressing pre-rasterized text in a bitmap format, then the original text that produced such a pre-rasterized form shall also be required to be present in TT AF content.

The current draft of TTML2 does not enforce the second part of the requirement, and permits that original text be omitted from the TTML content.
