RE: Working with Collections

You say you want to combine all the documents into one big document. You can
certainly do that, for example

<xsl:variable name="bigDoc">
  <xsl:copy-of select=="collection(...)"/>
</xsl:variable>

But you also say that this gives you memory problems. So I think you need to
explain why you feel you need to do this. You say "I need to be able to
traverse the entire collection" but that doesn't appear to justify doing it
this way.

What transformation are you actually trying to perform?
