MathML test suite feedback

MathML test suite feedback

Hello,

I've compiled with ConTeXt a large excerpt from the MathML 2.0 Test Suite  
(http://www.w3.org/Math/testsuite) and I encountered the following  
problems (test cases attached):

- Percentage in tag attributes are not correctly handled (seem to be seen  
as tex comments) and make context crashes.
- mfenced with empty separators doesn't work.
- Using different brackets in <mo> doesn't work.
- I don't know if it's a local install problem, but some fonts are not  
found when using UTF encoding.

This said, only 6% (41/657) of the tests fails, which is an excellent  
rate. BTW, if someone is interested in the big context file containing all  
the tests, just tell me. I can also send the perl script used to generate  
this doc.

Regards,
BG

i assume that you ran with \usemodule[mathml]

how does \usemodule[newmml] perform? that one should work better with utf

if you prepare a file with 'failures' i can have a look at it

ah, you attached the problematic files; i'll have a look

\startXMLdata does not change the catcode of % and it grabs an argument; 
could be a low priority feature request ( to be added to the 
wiki/collector)

best use:

\startXMLbuffer

\stopXMLbuffer

\processXMLbuffer

(the fontsize is not supported (does not make sense in a regular 
typesetting context)

you say:

\starttyping
    <mml:math xmlns="http://www.w3.org/1998/Math/MathML">
      <mfenced separators="" open="" close=" ">
        <mi>x</mi>
        <mi>y</mi>
      </mfenced>
    </mml:math>
\stoptyping

is rendered as:
\startXMLdata
<math>
      <mfenced separators="" open="" close=" ">
        <mi>x</mi>
        <mi>y</mi>
      </mfenced>
    </math>
\stopXMLdata


\startbuffer
    <mml:math xmlns="http://www.w3.org/1998/Math/MathML">
      <mfenced separators="" open="" close=" ">
        <mi>x</mi>
        <mi>y</mi>
      </mfenced>
    </mml:math>
\stopbuffer

\typebuffer

is rendered as:

\processXMLbuffer

saves keystrokes and is less error prone (differences in code)

Thanks for the advice. Indeed it is shorter and much more elegant. But in  
this case the test was automatically generated.

Actually the code is different because the XML namespace does not seem  
correctly handled.
For example, this does not compile:

\startXMLdata
   <mml:math xmlns="http://www.w3.org/1998/Math/MathML">
     <apply><divide/><ci>1</ci><ci>6</ci></apply>
   </mml:math>
\stopXMLdata

But this compiles:

\startXMLdata
   <math>
     <apply><divide/><ci>1</ci><ci>6</ci></apply>
   </math>
\stopXMLdata

maybe we should start thinking of 

texmf/samples/context/third/mathml/..

kind of archives, test suites, regression tests etc (preferable maintained by some users -)
