No. Paul's proposal is to add a parse-string-as-xml() function. This is
essentially nothing at all like node-set() as it currently exists in
xt/saxon/xalan extension namespaces.

All conforming processors treat non empty variable and parameter
elements as constructing result tree fragments, and empty variable
and parameter elements as constructing node sets (or other types such as
boolean, string or number).

MSXSL is currently experimenting with having these non empty forms
construct node sets, but hopefully it will conform by the time it comes
out of `preview' release.
