Since nothing in TTML cares about how schemas are used or where their
resources reside, then this is really out of scope for TTML the spec.

Actually, this has changed after we realized that CSS and XSL-FO forbid
negative values for width and height. See the new text
under file:///Users/glenn/work/w3c/ttml/ttml10/spec/ttaf1-dfxp.html#style-attribute-extent.

The answer is that there is no requirement for a region to be contained in
the root container region.

The definition

Root Container Region

A logical region that establishes a coordinate system into which *Document
Instance* content regions are placed and optionally clipped.
indicates that clipping of the RC is optional, so that is "document
processing context" specific issue as defined.

A use case for having a region appear outside of the RC is to fly the
region into or out of the RC via animation.
