Re: ACT TF Meeting Agenda Thursday 9 January

Hey Kathy,
Thank you for the feedback. To make the change you're asking for, we'd no
longer allow grandfather tags. For example the primary language subtag for
"i-klingon" is "tlh" if you processed the language using BCP 47. If instead
we were to match based on what comes before the first dash, the primary
language subtag would be "i", which would fail the rule despite having a
valid language tag. However, since grandfather tags are uncommon, and have
been superseded with three-letter language codes, I think this is a
reasonable trade-off.

On the other hand, current browsers seem less strict with matching
languages as you suggest. Using the :lang(en) pseudo class does match
"en-US-GB", despite that not being valid BCP 47. I talked to Kasper, and we
are going to update the rule to be in line with the way the CSS lang
pseudo-class works.

Wilco
