I am honoured with so much attention for such a seemingly simple question ;)
Inside a function, apparently, the node is recreated on each function
call. Whether it is this:
<xsl:function name="my:getNode"><node /></xsl:function>
<xsl:function name="my:getId"><xsl:value-of
select="generate-id(my:getNode())" /></xsl:function>
or whether you use variables to achieve the same result. Apparently, the
node need not be part of the result tree to achieve this effect (maybe
it is, I don't know, but it is never output at least).
The variable-inside-one-function (like David's solution) is the one I
currently employ, but any variant is likely to succeed if I understand
Michael Kay correctly.
