CSS3 writing-modes inline-alignment test suites

Hello,

I would like to contribute wring-modes tests, especially for related
to inline-level alignment property[1].

I have already written five tests and I attach it to this mail.
Could you review it or give me some comments?

Also, I have a question about the writing-modes specification.
In 4.3 Atomic Inline Baseline, there is the statement "alphabetic: The
alphabetic baseline is assumed to be at the under margin edge.".
Does 'at the under margin edge' mean 'at the under margin edge **of
inline block**'?
I think that 'under margin edge of inline block' is too low position
for inline alignment.
