The people who define SQL, H2, decided to support XQuery for querying 
XML. They started by trying to extend SQL, there have been many 
proposals to do that, but they concluded that supporting XQuery from 
within SQL was important.

Dimitry's SQL5 is not a language that H2 would recognize as SQL.

I think the industry has been adopting SQL for querying relational data 
and XQuery for querying XML. These languages have been widely perceived 
as good languages for the tasks they were designed for. Since these are 
the standards, and they do the job well, they are likely to remain in 
place.

Who is actually using SQL5? Is anyone besides Dimitry pushing it?
