DOCBOOK: XML, XSL, texmath inlineequation not.

[Doug du Boulay <ddb@R3401.rlem.titech.ac.jp>]

Hi,
I was trying to use  the //OASIS//DTD DocBook XML V4.2//EN
with the xsl  stylesheets version 1.50.0 to create a mathematics 
oriented document using the texmath attributes.

Basically I set the following variables in my style sheet

<xsl:variable name="tex.math.in.alt">latex</xsl:variable>
<xsl:variable name="tex.math.delims">0</xsl:variable>

and then invoked  
<inlineequation> <alt role="tex"> \( \hat{R} = \hat{R}(X,Y,Z) \)
          </alt> <graphic fileref="figures/xc0.xbm"/>
</inlineequation>

running this via saxon  and latex I do get  a very nicely formatted 
equation in the resultant single page html document, but unfortunately the 
inline equation is not inline, but is wrapped front and back with </p><p>

Is there a simple fix for this?
thanks 
Doug
