SQL instead of XQuery

Good day,

Usage of XQuery for processing of xml-data in DBMS
is practically equal to existence of second, foreign query language.
I propose to use SQL instead of it - let me introduce my view in
http://sql50.euro.ru/sql5.ppt (707 Kb, slides #31-47).
Accepting this proposals, we get smoothness between rational and xml.

I'd like to listen your critique.

P.S.
