DaveP I'd go further, and request that processors warn users, even if they don't fall over or blow up or report an error. That would be better than just warning in the spec, but without completely ripping up xpath2 and starting over it's not really possible. Most of the Backward Compatibility behaviour in xpath2 and xslt2 is local: you set the BC flag and something acts a bit more like it did in xslt1 within the scope of that setting. But RTF usage is different it has a pervasive nature, You have <xsl:variable name="x" vesion="1.0"> <x/> </xsl:variable> The spec could define that this did not produce a document node but instead (as in 1.0) produced something that was almost the same as a document node, but could not be used with / or []. The trouble is that that restriction would then have to be enforced for the rest of the scope of this variable, even in the bits of the stylesheet not using BC mode, so that select="$x/x" made an error. Thus this rtf type would have to be a full part of the Xpath 2 type system, with its entries in the data model, formal semantics etc this wouldn't be impossible but even I might admit this is asking for a lot of specification work and implementation effort just to raise an error.
