I think in this case generate-id() will be applied on the same node
again and again and will return the same string -- this is why I want
always to have a new copy of it -- or am I wrong?
no a literal result element like <x/> is (more or less) the same as using
<xsl:element name="x"/> it's a single node in the stylesheet but it
generates a new node each time it's executed, and generate-id() is being
applied to that result. You don't need an element at all of course, a
text node will do
<xsl:function name="pref:myId" as="xs:string">
<xsl:variable name="myNode">x</xsl:variable>
<xsl:sequence select="generate-id($myNode)"/>
<xsl:function
(you can't use
<xsl:variable name="myNode"/> as that generates a zero length string
not a node at all, for reasons of xslt1 cmpatibility)
