Hello ConTeXters.
I am using the wonderful ability of ConTeXt to directly typeset MathML equations, and have come across a problem with trying to put a line above a character using the <mover> element. Here's what I try:
\setuppagenumbering[state=stop] \starttext \startXMLdata <math display="block"> <mover accent="true"> <mi>x</mi> <mo>¯</mo> </mover> </math> \stopXMLdata \stoptext
The output I get is as if the accent="true" attribute wasn't set - i.e. the line is a long way above the x, not like an accent.
Is there another way to place math accents in presentational MathML?
My versions: TeXVersion 0.1 / Taco Hoekwater 2004 texexec : TeXExec 4.4 - ConTeXt / PRAGMA ADE 1997-2004 texutil : TeXUtil 8.2 - ConTeXt / PRAGMA ADE 1992-2004 tex : pdfeTeXk, 3.141592-1.11a-2.1 (Web2C 7.5.2) context : ver: 2004.8.15 cont-en : ver: 2004.8.15 fmt: 2004.8.22 mes: english
(PS (Patrick) - I tried to get a minimal file working on live.contextgarden but couldn't get any maths formatting to come out. Perhaps MathML support is not enabled there?)

Normal: \startXMLdata<math><mover ><mi>a</mi><mo>¯</mo></mover></math>\stopXMLdata \par
Accent: \startXMLdata<math><mover accent="true"><mi>x</mi><mo>¯</mo></mover></math>\stopXMLdata \par
\stoptext
now, the problem is that this funny char between <mo></mo> has to become a math accent, so what is the code? (name) someplace we need to handle that kind of things
