Re: clever ways to dynamically copy/create element st

Using parse-xml() to parse a literal string at run-time is going to be pretty
inefficient (although it might be optimiser if you're lucky). It might be a
bit more wordy, but a global variable

<xsl:variable name="empty-prolog" as="element(prolog)">
  <prolog/>
</xsl:variable>

is going to be a lot more efficient.
