Re: parameters in XSLT 2.0

For example, first I have this variable to [expletive deleted] in outside data:

   <xsl:variable name="raw-biblist">
     <modsCollection xmlns="http://www.loc.gov/mods/v3"
       xmlns:bib="http://purl.org/NET/xbiblio/citeproc">
       <xsl:copy-of select="$bibrecord/*/mods:mods"/>
     </modsCollection>
   </xsl:variable>

It's certainly not obvious that copying the source data in this way is
achieving anything useful.

Possibly: I can't see what the apply-templates calls are doing, so it's hard
to tell. If the apply-templates calls are creating new elements, then
there's probably no extra cost (in fact it may be cheaper) to wrap these
elements in a document node (a temporary tree). If there's a saving to be
made, then it will be made by avoiding creating new nodes (or copying
existing nodes).

Two things are worth remembering about performance engineering:

(a) don't tune your code unless it is failing to meet its performance
requirements.

(b) the only way to know whether your tuning attempts are worthwhile is to
make measurements before and after.
