RE: [xsl] key() and ordering of resulting node-set

["Michael Kay" <mike@xxxxxxxxxxxx>]

In XSLT 1.0, key() returns a node-set - a set of nodes with no intrinsic
order.

Operations like xsl:for-each and xsl:apply-templates, in the absence of
xsl:sort, will always process the nodes of a node-set in document order. (If
they don't it's a bug.)
