Except that in XSLT 2.0, this could also match a parentless element

Arguably, you wouldn't want to talk too much about parentless nodes
straight away, though in any introductory history of the XSLT standards
there's a good chance the concept would be mentioned as one of the
things added in XSLT 2.0.

Michael Kay's version from this morning is (unsurprisingly) clearer for
expressing an XSLT 2.0 identity transform.  IMO, trying to cover both
XSLT versions at once is counterproductive since it's easy enough to
have two version-specific boilerplates that you copy as needed.

Why not 'child::text()', etc., here if it made it more understandable
