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.

So:

<xsl:variable name="foo">
  <a/>
  <b/>
</xsl:variable>

here a/following-sibling::b returns true


<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.
