Re: IMSC Hypothetical Render Model

I put the issue,
https://github.com/w3c/imsc-hrm/issues/23

Text below.
*Is there a label I should put to ease our tracking?*

=========ISSUE TEXT=============

I am inquiring on behalf of APA WG:

APA understands that the specification relates to subtitles rendering.

Captions and other such synchronized streaming text is critical to many
accessible user experiences, and indeed WCAG is cited in the referenced
specifications TTML and TTML Profiles.

Our question is: if the IMSC Hypothetical render model (specified here)
decides that complexity exceeds the capability of the system to render, and
returns an error message, should readers of this specification be alerted
that this error impacts the accessibility of the system? Or are such error
states already handled in the parent specifications, and this document is
only a low level API without any impact on the experience of accessibility?
