  This is not related to EXSLT.  General XSLT questions are best asked
on XSL List at Mulberry Tech.

  From the top of my head, I'd say that this is the purpose of xsl:key,
though not stated explicitly in the REC (that's up to the
implementation.)  Saxon for instance (if I am right) creates an index
for a key at its first use.
