It would appear that this makes -1,0,2,1 an ascending sequence. I dislike
this "empty-is-false trick" - once in a while you get bitten.
count($seq) < 2 or ...
Yes, good to remind that we are dealing with items -- not just nodes.
count($seq) < 2 or ...
No, the idea is to avoid count, as this may add the time for one
unnecessary pass over the sequence. And the solution can be adjusted
naturally:
<xsl:function name="my:increasing" as="xs:boolean">
<xsl:param name="pSeq" as="item()*"/>
<xsl:sequence select=
"empty($pSeq[2])
or
$pSeq[1] lt $pSeq[2] and my:increasing(subsequence($pSeq, 2))"/>
</xsl:function>
