Re: [IMSC1 + TTML] Explicitly allowing space around commas in tts:fontFamily attribute values

For (a), shouldn't you be asking whether an implementation rejects or might
abort or otherwise discard content if spaces DO appear? Implementations
would not INSERT spaces. It is authors that would insert spaces.

Good morning/evening,

As described at [1], there is an ambiguity around the presence or
absence of spaces around comma delimiters in tts:fontFamily.

[1] https://github.com/w3c/ttml1/issues/248

Two potential approaches are suggested. Please indicate your
preference and/or share data points at [1] or on this thread.

In particular, does your implementation (a) insert spaces around
commas in tts:fontFamily attribute values and/or (b) accept spaces
around commas in tts:fontFamily attribute values?

Thanks,
