One advantage of sequences is that you can store sequences
of strings etc ("a","b", ....)
Similarly inside
<xsl:for-each select="zzzz">
<xsl:sort select="mmm"/>
the current node list is the ordered list sorted by mmm but
that list can not be saved in order, if you need it again
later you have to re-sort. In XSLT2 sorted sequences can be saved.
DaveP:
<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?
Other reasons have to do with alignment with xsd schema but
they are,
natutrally:-) almost all bad, but on balance ordered
sequences are probably a good thing (although perhaps they
might have been better still if they had allowed sequences
of sequences)
<grin/>
regards DaveP
