The input to XSL is a tree in which there is a complete order applied to the set of nodes. This ordered input tree does not change during a run. The "implementation defined" variability is in the way the ordered tree is built from a linear XML syntax. As Mike commented Saxon will give different results with different parsers, as the XSL engine will have effectively been handed different ordered trees. (In fact its probably the XSL code building the tree from sax events rather than really being passed an XPath tree model, but that is an implementation detail) Of course there need never have been any linear input at all. MSXML for example gets its input from a DOM object, that may have been manipulated in memory with attributes added/changed/deleted etc. Again the end result has to be ordered somehow before XSL starts work but it isn't specified how that ordering is done. Once MSXSL gets that tree though, it is fixed for the duration of the stylesheet.
