Re: Wish List: Allow <xsl:choose> within <xsl:call-template>

["Alexandra Morgan" <lexalex@xxxxxxxxxxxxx>]

Nikita's snippit is interesting, but would it actually work? Section 11.5 of www.w3.org/TR/xslt states "...the binding is visible for all following siblings and their descendants." I read this and took this to mean that once you've passed the end of the element that's the parent of the xsl:variable element, the variable is gone... which, in this case, would mean that $par_one is only bound inside the xsl:when. Not very useful, I thought, but otherwise I don't know what they mean.

I would test this myself, but I can't seem to get variables working at all....
