With Diazo/plone.app.theming you can merge attributes from the template and content, see: http://diazo.org/basic.html#merge

If you can't upgrade then you'll need to do this with inline XSL, something like:

<prepend theme="/html/body" css:if-content="body.template-contact-info"><xsl:attribute name="class"><xsl:value-of select="/html/body/@class"/> styled-form</xsl:attribute></prepend>

Update: I forgot the tag in the example above. It should work now.
