Answer 1

Your instruction:
<xsl:for-each xml:id="id_33" select="row[generate-id() = generate-id(key('keyHeader', nsmpr0:PID)[1])]">
selects nothing because there is no element named row in the current context (or in the entire input document, for that matter).
Side note: your stylesheet is tagged version="2.0" yet you are attempting to use Muenchian grouping - which makes very little sense.

Answer 2

I pasted the code which worked, just for others in case anybody want the code
