XSLT 2.1: Nestable sequences or sequence references?

  Hi,

  I've digged a bit into the W3C bugzilla, but didn't find
anything.  Is there any plan to introduce some kind of
nestable sequences or sequence references in XPath or XSLT
2.1?

  By nestable sequence, I mean a kind of sequence that is not
automatically atomized.  For instance:

    sref:make-sref((1, 2)), sref:make-sref((3, 4))

would be (pseudo-code):

    ( (1, 2) (3, 4) )

that is, a sequence of two sequences (of each two integers.)

  Regards,
