Mathml test suite - error

Hi,

I begin to test my solution with testsuites from
http://www.w3.org/Math/testsuite

The image for this test is not good.
http://www.w3.org/Math/testsuite/build/main/General/GenAttribs/style2-full.xhtml

It is good here if I send the errors from testsuites?

And a question.
Where is the documentation for math tag ?
I see now, in MathML 3, we can add a lot of attributes into this tag like:
display="inline",  display="block", mode="display", macros, bevelled, ...


thank you
