I agree with this plan.

Thank you for your good explanation.
Now I think that a choice of color (blue and yellow) is right way.

3. About test case title

When I reviewed your test, I guessed that the combination of opposite side
('float-*left*' with 'veritcal-*rl*' and 'float-*right* with
veritcal-*lr*') is important for test. So I thought that it is better to
add its value in test case title.
If there are 'float: *right*' with 'vertical-*rl*' (and 'float: *left*'
with 'vertical-*lr*') in tests, I will feel that the absence of float value
in title is not strange.

4. About missing test case
> In my mind, when testing 'writing-mode', I would do all and each
'writing-mode' values in the order they are listed in the spec:
horizontal-tb, vertical-rl, vertical-lr, (default or initial) and inherit.
Now, testing 'writing-mode: horizontal-tb' does not make much sense. IE5
and NS4 could and would pass those tests, you see. And testing default or
initial values is impossible to test. Many (otherwise, all) tests we did in
CSS2.1 about initial and default property values were not useful. So, there
is no line-box-direction-*004*.xht because there is no test about default,
initial 'writing-mode' value. I could remove

CSS rendering engine) manufacturers.

OK, I understand what you said.
However I think that a lack of number makes tester (or developer) feel
strange.
Will you do re-numbering these test case to remove a lack of number?

Hajime.
