  A good timesaving is to put it into a variable at the root of the
  template...

  	<xsl:variable name="mapping" select="document('mapping.xml')/root"
  />

  Then use the variable instead of the document


Many systems store the result of document() in memory and so using it
twice should take no longer than saving it in a variable. Conversely
there's nothing in the XSLT spec that says a system has to store the
result of a variable rather than re-evaluating it each time it is
referenced.  However if for a particular XSLT system this does reduce
loading/parsing then it would be a saving, yes.
