Right, I think text layout should be done using OpenType defaults (i.e. kerning on, common ligatures enabled, etc.) with author-controlled ways of modifying those defaults. I'm going to add a concise explanation of this, that's what I meant by the "still to be done" item below: > Still in progress: > - Better wording describing OpenType default behavior, including kerning I'd actually prefer to refer to the OpenType spec directly as the normative reference for what these defaults are but that spec is sometimes unclear about whether a given feature is enabled by default or not. For example, are old-style figures enabled or not by default? My reasonable guess is they're not (that makes more sense) but the OpenType spec just says "Users can switch between the lining and oldstyle sets by turning this feature on or off." I think that may be a bug in the spec, if a designer uses old-style figures as the default glyphs for numerals then the statement above will be incorrect. Cheers, John
