nigelmegitt has just created a new issue for 
https://github.com/w3c/imsc:

== Image profile documents generate no ISDs ==
According to TTML1's [construct intermediate document] process in 
ยง9.3.2 _empty_ content elements are pruned. Since image profile 
documents are not permitted to contain `p`, `span` or `br` elements 
and entities in other namespaces are ignored, the `div` elements are 
all empty according to TTML1 and will be pruned, resulting in there 
being no ISDs generated at all. I think some wording in IMSC may be 
needed to indicate that for the purpose of ISD generation a `div` 
element with a resolvable `smpte:backgroundImage` attribute shall not 
be considered empty.
