Taka,

please verify again:

http://test.csswg.org/source/contributors/east-tokyo/submitted/css3-writing-modes/text-combine-horizontal-010.xht

and text-combine-horizontal-011.xht
and text-combine-horizontal-012.xht



Another method of writing title text in a consistent and predictable
manner can be:

<title>CSS [Name_of_module] Test: [property_name]: [property_value]
 [optional: some_additional_parameters]</title>

like:
<title>CSS Writing Modes Test: text-combine-horizontal: none</title>

Well, then it just means that we can not create a reftest for such test.

The test could still be testing '13' though. When a reftest can not be
created, then it just mean that we can not have a software compare
pixel-by-pixel a screenshot of test with a screenshot of reftest.

A test can be created even though a reftest for it can not be created.
This is where a test can be and will be evaluated as passed or failed
according to a human tester.

One idea would be to reuse the figure 18 example
"Example of horizontal-in-vertical tate-chu-yoko"
from the spec and write a flexible, appropriate pass/fail conditions
sentence for it.

2 Examples given:

More..

1.
<p>Test passes if the upper block is <strong>identical</strong> to the
lower block including <strong>layout</strong> and
<strong>orientation</strong> of each characters.</p>

If you say that 2 things must be identical, then, generally speaking,
people will observe very strictly, very carefully and thoroughly. So,
I'm not sure if "including <strong>layout</strong> and
<strong>orientation</strong> of each characters." is really or
absolutely needed. If you think so, then

<p>Test passes if the upper block is <strong>identical</strong> to the
lower block, including orientation of each character.</p>

The most important word in the test is "identical".

You could also reword the pass/fail test conditions sentence to be saying:

<p>Test passes if there are 2 <strong>identical</strong> rectangles with
identical orientation of characters.</p>

2.
In reftest

http://test.csswg.org/source/contributors/east-tokyo/submitted/css3-writing-modes/reftest/text-combine-horizontal-010-ref.xht


line 25 #test
	{
	}
	.tcy  /* tate-cyu-yoko: horizontal-in-vertical */
	{
		text-combine-horizontal: none;
line 31 }
line 32	#control
(...)
line 42 <div id="control" lang="ja">...
line 44 <div id="control" lang="ja">...

Remove lines 25 to 31
and replace lines 32, 42 and 44 with

line 32	.control
(...)
line 42 <div class="control" lang="ja">
line 44 <div class="control" lang="ja">


Same issue with text-combine-horizontal-011-ref.xht and
text-combine-horizontal-012-ref.xht

3.
line 10:  <meta name="flags" content="font should" />

"should" flag should be used only when a CSS feature is recommended and
not required by the spec. Here, the text-combine-horizontal values are
required. So, here, you can safely remove the "should" flag from
text-combine-horizontal-010.xht and text-combine-horizontal-011.xht (and
probably text-combine-horizontal-012.xht too).
