I don't think that's right. By definition node-set is "an unordered 
collection of nodes without duplicates". So all dublicates have to be 
removed at the time of XPath expresison evaluating and the order may be 
any one appropriate to XPath processor.

<xsl:copy-of> copies nodes in document order, but if you are copying 
attributes, why do you care about any order?
