    XSLT2 (and Xquery) allow you to make and query elements in
    a single transform  and allow sequences of elements. If you
    want to make a sequence <a/> <b/> <c/> you might have
    expected it should be

    <xsl:variable name="x">

Groves... no, I can't say that. 'bushes'?
I think Mike Kay was right suggested they should be allowed,
until you said...

    That's often convenient but sequences have different
    properties. Not sharing a parent means that they are not
    siblings for example.
MMM. Yes, I guess the 'distantCousin' axis might be a problem :-)

      " match="//stone" will only match a stone element that
    belongs to a document tree. "

      Does the match just fail .... or is it an error? Suck it and see?
      Then recall that match="stone" works similarly (in 1.0)
    to //stone.

    It's not an error it just doesn't match.  If you look back
    in this thread at Wendell's explanation of why //stone  and
     stone match the same thing you'll see that it essentially
    depends on the fact that every element is the child of
    _something_ either another element or a document node. In
    XSLT2 that is no longer true as it gives access to
    intermediate results, you can query an element after it has
    been constructed but _before_ it has been copied into the
    final result tree. Such a free standing element has no

Perhaps WG prudishness is avoiding the obvious axis name then!


    This is OK I think. It's a bit technical but you can't
    generate parentless elements by mistake, and you can't
    apply templates to them by mistake. If you know enough to
    do both of those things on purpose, then you'd better know
    not to use //foo unless you mean it.

All of which leaves a nasty feeling that W3C are digging holes for the
A clean break with xslt 1.0, and a smartish stylesheet to do most of the
might have been a better solution.
  So XSLT 3.0 (if 2.0  lasts) will also be considering these oddities?

Agreed its logical... but is backwards compatibility mode all that good

Thanks for the explanation David.
