buffers and mathml

[<jimarin@bayesinf.com>]

Hi all,

I hope not to be posing a silly question.

I am trying something like:

usemodule[mathml]
\starttext

\def\open
{<}

\def\close
{>}

\startbuffer
\open math display="block"\close
\open apply\close \open sin/\close \open apply\close \open plus/\close
\open cn\close 2 \open /cn\close \open ci\close a \open /ci\close
\open /apply\close \open /apply\close
\open /math\close
\stopbuffer

\processXMLbuffer

\stoptext

But this does not pass to \processXMLbuffer the result of substituting
commands \open and \close...

how could this be achieved...?

I know that I could have used myself the < and >'s instead of the ugly open
and close but that is not my requirement.

I tried defining a command

\def\Wea
{
\open math display="block"\close
\open apply\close \open sin/\close \open apply\close \open plus/\close
\open cn\close 2 \open /cn\close \open ci\close a \open /ci\close
\open /apply\close \open /apply\close
\open /math\close
}

and then...

\startbuffer
\Wea
\stopbuffer

but that is plain wrong...



thanks

jima
