IS there any way to serve an xml document with embedded MathMl in a 
format other than xhtml, especially if the xml document contains a 
link to an xsl stylesheet which

a) causes the browser to reformat its content as xhtml
b) includes mathml.xsl via an xsl:include or xsl:import instruction

and get the MathMl to display properly? If there is a way, I have not 
had success in finding it.
