Math and MATHML problem

1 Jun 2005

      Hello,

I'm trying to typset some math.

when I use \startbuffer ...here mathml ...\stopbuffer and a following
\processXMLbuffer I get a nice centered formula. When I save that code
to a file  myeq1.xml and try to include it with
\processXMLfile{myeq1.xml}I compillation stops at that point.
\processXMLfilegrouped{myeq1.xml} produces a formula again but 2
additional symbold appear at the beginning of the formula.

Questions:

- What is my fault?

- Whow can I set the alignment of formulas (ie leftaligned)?

Thanks for any help

\usemodule[mathml]
\defineXMLentity [PartialD] {\getXMLentity{differentiald}}
