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?

(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?)

\stoptext now, the problem is that this funny char between <mo></mo> has to become a math accent, so what is the code?
