Updates to section 10.8.1

I'm still trying to understand the line layout formatting that is 
described by CSS 2.1. Having read Mike Eric Meyer's inline formatting 
model 'cheat sheet' at http://meyerweb.com/eric/css/inline-format.html, 
I believe it describes what most browsers do (more or less), but I don't 
like what I see from a typographical point of view.

I would expect growing the line-height to cause the typographical 
distance between lines to grow and for the *whole* content on each line 
to be centered vertically *without* affecting the vertical distance 
between inline elements on that line.  That makes sense from a visual 
point of view. Applying half-leading individually and independently on 
each inline non-replaceable element is just plain wrong, in my mind. The 
behavior is inconsistent w.r.t. use of replacable vs non-replacable 
inlines at the very least, and basically prevents the vertical-align 
property from being used on text.

Consequently, I'd like to propose these minor tweaks to the CSS 2.1 spec 
(or rather CSS 2.2?) :-)

First paragraph of 10.8.1:
Change "/The difference between the content height and.../"
To "/The difference between the content height *of a line box* and.../"

Second paragraph of 10.8.1:
Change "/User agents center *glyphs vertically in an inline box*, adding 
half-leading on the top and bottom./"
To "/User agents center *line boxes *vertically, adding half-leading on 
the top and bottom./"


 From a technical point of, I believe these change would make rendering 
easier (it would for my UA at least), it would give the result you 
expect from a typographical point of view (see above), and it would let 
you use vertical-align with text.

Any comments?
