"loca" - a typo?

[jsbien]

It occurs twice in the manual, but perhaps you mean "locl"?

[alerque]

No, loca is part of the OpenType spec.

[jsbien]

Thanks! Are you sure it is used in the manual in this meaning?

[alerque]

Nope, only that it makes sense to see in the context of a font with lots of OpenType features.

Yes.
Those are discussing the feature tag locl not the table loca.

A mistake. Thanks for catching it--I have corrected it now.

[jsbien]

Glad I could help. BTW, you seem to use aalt, which is not mentioned in the manual.

[psb1558]

I don't think it's possible to document aalt usefully, since the number of variants in it is enormous, and it is likely to change from release to release. Also, users don't generally (and shouldn't, because of the instability) use aalt directly; instead it's used by apps like InDesign to construct a glyph palette.

OK
