ISSUE-176 (extent and origin on blocks): Adding support for extent and origin attributes on block elements [DFXP v.next]

Raised by: Sean Hayes
On product: DFXP v.next

It has become common practice to use the extent and origin attributes directly on block elements (specifically <p>), as this greatly simplifies authoring and conversion process. This is essentially akin to creating 'anonymous' regions for each block, or relative positioning in CSS.

The TTML 1.0 spec allows this syntactically but did not specify any meaning. We should resolve this by supplying reference semantics for the practice.
