Re:  1st previous node()
I have now.  I've just noted that in an xml like this:

<a>
 <b>
  <c>
    <e></e>
   </c>
 </b>
 <x>current node</x>
<a>

Given <x> is the context node, the preceding element is <e>, but I am
expecting <b> So I now have something like this:
<xsl:variable name="previous-nodes" select="ancestor::*[1] |
preceding-sibling::*[1]/>
The ancestor select is necessary because if the preceding <b> node did
not exist then the correct node match would be <a>.

So then previous node is:  $previous-nodes[last()]

See any issues with the above?  Let me restate what I am after:

Select the first preceding sibling node if exists, or select the first
ancestor node, if exists.

I have another question about generating id's.  Will the results be
the same regardless how you get to the node()?  I seem to be getting
different answers, but this is not conclusive.

Karl..
