What's the issue there?

It should really have have a return type of item()*, and the param
should really be called 'node-list' rather than 'context':

<xsl:function name="f:apply-templates" as="item()*">
   <xsl:param name="node-list" as="node()*"/>
   <xsl:apply-templates select="$node-list/>
</xsl:function>

anything else?
