Whenever you think of xsl:function (or xsl:sequence) as source of 
intermediate result,
that you won't output in the tree immediately, you notice that xsl:sequence 
is more efficient:

<xsl:function name="t:add" as="xs:integer">
 <xsl:param name="first" as="xs:integer"/>
 <xsl:param name="second" as="xs:integer"/>

 <xsl:sequence select="$first + $second"/>
</xsl:function/>

...

<xsl:for-each select="1 to t:add($first, $second)">
  ...
</xsl:for-each>
