This may be inefficient (depending on the XPath engine being used).

I think the following has better chances of being more efficient --
write an xsl:function, name it, say, "increasing". The body of this
function can be just:

    not($seq[2])  or $seq[1] lt $seq[2]  and  increasing(subsequence($seq, 2))
