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.
