It would be VERY nice having support form parametric XSL through <xsl:apply> tag; it could be something like: <xsl:apply ...> <xsl:params> <xsl:param name="xxxx">value</xsl:param> <xsl:param name="yyyy">value</xsl:param> <xsl:param name="zzzz">value</xsl:param> </xsl:params> </xsl:apply>
This feature won't be added. The XSL taglib will be deprecated soon since it uses Xalan1 which is deprecated and the XTAGS and Standard taglibs provide a better alternative.
