Ah.... thanks for the explanation. That clears up a lot :-)
It's worth adding the when you do as="element()+" the elements
represented by that variable aren't siblings because they don't have a
common parent.
<xsl:variable name="foo" as="element()+">
<a/>
<b/>
</xsl:variable>
here a/following-sibling::b returns false
...so it's worth bearing that in mind when deciding what the as
attribute should be.
So
<xsl:variable name="foo" as="document-node()">
<a/>
<b/>
</xsl:variable>
would be the equivalent of (identical to?) an un-typed variable and
allow siblings?
