Re: A more complicated Muenchian Method exercise

  but the conversion of the OR'd set to a string does not work.  It seems to
  ignore the rec_id, and I only get the sender set.


Yes, it is a general feature of Xpath1 string functions, that if you
give them a node set and theey want a string, they take teh firat node
of the node set and take its string value, and junk everything else.

I think you just want two xsl:key statements:

<xsl:key name="key2_name", match="header" use="concat(arrive_date, ' ', sender/sen_id )"/>
<xsl:key name="key2_name", match="header" use="concat(arrive_date, ' ',sender/recipient/rec_id )"/>


multiple xsl:key statements with the same name form a combined key.
