Found it!
You nevertheless brought something up: why not simply *create* the node 
each time again?. Here's a simple enough (but process intensive) solution:

<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>

this generates unique ids, even on recursive calling of the function (if 
the for-each is wrapped inside a function). Not sure this is "REC 
behavior", but it sure does what I want. Maybe someone can confirm that 
this is indeed the expected behavior and that I can rely on the method 
to return a unique id value within the same process.

This may also suit requirements where a random, unique value is needed, 
though "random" is not really what is being generated. I get: d28, d29, 
d30 etc.

Thanks for looking into it,
