<xsl:variable name="sortedSequence">
      <xsl:for-each select="zzzz">
       <xsl:sort select="mmm"/>
  </xsl:variable>

  Is that the sort of thing you mean David?
  the variable now holds the sorted sequence?


No, if you do that the variable will hold a document node which contains
the zzz elements as children.

You need an as="element()*" on the variable to stop it making teh
documet node (which it does mainly for XSLT 1 compatibility)

There are other ways of ending up with an ordered sequence, teh most
dirst being

<xsl:variable name="x" select="(a,b,c)"/>

which stores any elements selected by a followed by elements selected by
b followed by elements selected by c, in that order, whatever order they
are in in the source.
