And that this felt non-analogous to the following: > > <xsl:function name="my:rootless"> > <test1 /> > <test2 /> > </xsl:function> What you're describing is the same as typing the variable as="element()" eg: <xsl:variable name="root" as="element()+"> <test1 /> <test2 /> </xsl:variable> By adding as="element()+" the variable goes from a root with two child elements that are siblings (eg to access <test1/> use $root/test1) to a sequence of elements with no root and that aren't siblings (to access <test1/> use $root[1]) > Thanks for any insightful insights ;) I don't know why it's like that - I'm guessing it's because they don't share a common parent that they aren't siblings, but I can't find anything to back that up. -- Andrew Welch http://andrewjwelch.com Kernow: http://kernowforsaxon.sf.net/
