I applied your comments to my tests and resubmitted it.

  1. replaced 'padding-{left|right|top|bottom}: 1.5em;' with
'padding-{left|right|top|bottom}: 1.0em;' and replaced the word
'yellow rectangle' with 'yellow square'.
  2. removed 'padding: 0.2em;'.
  3. replaced 'black block' with 'black strip'.
  4. changed class name 'top' to 'right-side-of-central-baseline'.
  5. removed class declare which is never used in
inline-block-alignment-006-lr.xht and
  7. replaced 'vertical-rl' with 'vertical-lr' at Line 48 of
  8. modified assert sentence for purpose of consistency in content of the test.

I misunderstand the writing-modes specification.

In seciton 4.2^[1], there is a sentence.
"In vertical writing mode, the central baseline is used as the
dominant baseline when ‘text-orientation’ is ‘mixed’ or ‘upright’.
Otherwise the alphabetic baseline is used. "
I believed that when 'writing-mode' is vertical and when
'text-orientation' is 'mixed or 'upright', the central baseline is
used as the dominant.

However I've found following sentence in section 5.1^[2].
"use-glyph-orientation: ... These properties are deprecated and do not
apply to non-SVG elements. ... In all other contexts, and for
implementations that do not support the glyph orientation properties,
the ‘use-glyph-orientation’ behavior is the same as for ‘mixed’. "
I think that it is correct to the baseline behaviour
'use-glyph-orientation'  is the same as 'mixed' or 'upright'.
So I removed a case of 'use-glyph-orientaiton' from alphabetical
baseline tests and added it to central baseline tests.
