How about something like:
<xsl:template match="page">
<xsl:variable name="someName">
<xsl:apply-templates/>
</xsl:variable>
<xsl:value-of select="task:addPage($task, string(@ident), $someName)">
</xsl:template>
The type of $someName should be an XRTreeFrag, I believe.
As far as the optional first argument, neither of those types is used
for extension functions. These are for extension elements. You can
specify an optional ExpressionContext as the first argument if you need
any of its methods.
