I should be and will be in vacation in a few days. I'll notify all the
committers from Japan.

I understand. It is difficult. One way is to use an image as reference
or use CSS transforms rotate feature as reference.

Example given of rotated text (45 degrees)
http://test.csswg.org/suites/css3-transforms/nightly-unstable/html/transform-rotate-001.htm

This text
"
for reference:
		horizonal-only:(Includes: Latin, Arabic, Hebrew, Devanagari)
		vertical-only:(Includes: Mongolian, Phags Pa)
		bi-orientational:(Includes: Han, Hangul, Japanese Kana)
"
should NOT be read by testers. You can leave it as a <!-- comment --> in
the test though.

I have been working on this.

One way to make the pass/fail conditions sentence short and simple to
understand is to create a test and a reference (image or SVG or
something else) and then simply say:

"Test passes if there are 2 <strong>identical</strong> [shape
descriptor]s."

where shape descriptor could be rectangle, stripe, bar, line, grid or
even "Text sample", etc.. In this way, you avoid having to describe in
great details the 2 shapes or text.

That way, you can also reuse later the reference in the reftest.

Yes. I agree.

Here's what I've been working on:

http://www.gtalbot.org/BrowserBugsSection/review/text-orientation-mixed-001-review.xht

http://www.gtalbot.org/BrowserBugsSection/review/text-orientation-mixed-001-review-ref.xht

http://www.gtalbot.org/BrowserBugsSection/review/text-orientation-mixed-123.xht

http://www.gtalbot.org/BrowserBugsSection/review/text-orientation-mixed-123-ref.xht

Another idea would be to use CSS transform rotate feature on <div
id="reference">:

"
 rotate(<angle>)
    specifies a 2D rotation by the angle specified in the parameter
about the origin of the element, as defined by the
‘transform-origin’ property. For example, ‘rotate(90deg)’ would
cause elements to appear rotated one-quarter of a turn in the
clockwise direction.
"
coming from
15.1. 2D Transform Functions
http://www.w3.org/TR/css3-transforms/#two-d-transform-functions

as the reference. That way, no image to create.

-----------

<meta name="flags" content="font should" />

You can remove the "should" flag from
text-orientation-mixed-001.xht
and
text-orientation-sideways-001.xht

"should" flag means that the property value or feature is recommended
and not required by the spec. Here, text-orientation values are
required, must be supported.

More later.
