if you don't use as then an xsl:variable with content and no select attribute produces a temporary tree, what we used to lovingly call a result tree fragment.
$x is (a sequence of one) document node that has a single text node child that has string value "hello"
<xsl:variable name="y" as="string?">hello</xsl:variable>
$x is (a sequence of one) string with value "hello"
Is this really the case? Does it really mean that the processor doesn't construct the temporary tree (and then atomise it?) - if so then it's really useful.
Yes, he didn't just make that up :) A not so fond farewell, more of a good riddance, to result tree fragments.
