[imsc] Offset <time-expression> w/o metric allowed?

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

== Offset <time-expression> w/o metric allowed? ==
TTML2 allows to specifiy an offset time `<time-expression>` without a metric, in which case the seconds metric applies. Currently this is not covered by any TTML2 feature (see w3c/ttml2#752), so it is neither explicitly prohibited nor explicitely allowed in IMSC 1.1.
