Behdad,
Can you confirm my understanding is that in HB:
1. For the script tags, one must use the ISO-style ("high level") script tags
to get script-specific shaping. You once told me the trick that using OT-style
("low-level") script tags would disable the script-specific shaper but still
execute the OT features blindly.
2. For the language tags, one should use high-level ISO-style language tags,
while the low-level OT languagesystem tags "might" work, but it's not
recommended to use them.
So overall, one should use the ISO-style codes.
