Re: Identity Transform

Close. In XSLT 1.0, whenever you process a node-set (using <xsl:apply-templates> or <xsl:for-each>, for example), those nodes are processed in *document order*. The attributes of an element always come before the children of the element, so whether you use "@*|node()" or "node()|@*", you always copy the attributes first. In XSLT 2.0 things are slightly different, in that each XPath 2.0 expression generates a sequence of nodes rather than a (by definition, unordered) set of nodes. However, when you use the union operator ("|" or "union"), the nodes in the resulting sequence are always sorted into document order, so again "@*|node()" and "node()|@*" return the same sequence of nodes.
