[css-values-4] typo for 'cap' unit description

[tshinnic]

In section 5.1.1. Font-relative lengths: the em, ex, cap, ch, ic, rem, lh, rlh units, under 'cap unit', text

If reliable font metrics are not available, UAs may determine the cap-height from the height of a lowercase glyph.

Yet, the next sentence mentions uppercase, and previously capital letters were mentioned. Should be s/lowercase/uppercase/ ?

Drat, forgot to include...

Same section, under 'lh unit' and also 'rlh unit', text

... converted to an absolute length by measuring the height line box containing only the strut ...

should likely be one of

• s/the height line box/the height that a line box/
• s/the height line box/the height of a line box/

Argh!
