Since it needs to be named "ModuleStart":
  select="...[self::processing-instruction('ModuleStart')]"

Can you explain how
   [not(self::text(normalize-space()))]
works?
I think it's supposed to filter out whitespace-only text nodes, but I
don't see anything in the spec about text() taking an argument.

Maybe you meant something like
    [not(self::text()[not(normalize-space())])]
?

Thanks,
