Re: How to use generate-id() inside an xsl:function w

The point is that generate-id() is not a random string
generator.  It generates an ID based on a node, always the
same ID for the same node.  If you call it without argument,
the context item is used (which is indeed not possible in a
function definition).

<xsl:for-each select="(1 to 20)" >
  <xsl:variable name="id-node"><some-node /></xsl:variable>
  <some-elem id="{generate-id($id-node)}" />
</xsl:for-each>
