I’ve updated the normative text for dir and lang based on the discussion in #1081 and https://www.w3.org/TR/string-meta/#bp-lang-dir-unknown.

@aphillips I’m unsure if (and from where) string direction and first-strong detection should be cited.

Looks good to me, but a suggestion for a small improvement

@aphillips, is there a plan to turn the i18n-glossary into a normative document? Otherwise we end up in a situation where we are using non-normative definitions in normative sections of the spec.

We would probably be interested in citing the auto (direction), string direction, and maybe base direction definitions.

Moved the discussion to w3c/i18n-glossary#78

I'll cite what you wrote there too, @christianliebel
