The implementation of exsl:node-set() in Saxon 6.x is a bit of a hack. A result tree fragment in Saxon 6.x is a document node, with a special bit set to say "I am a result tree fragment": this bit artifically disables operations such as "/" applied to the document node. The effect of exsl:node-set() is to unset this bit in situ, thus enabling such operations. A bit dirty, but the XSLT spec allows extension functions to do anything you like, so it's not technically non-conformant.
