It depends on your point of view.

The one you seem to be after is the first one, a schema language.

It is not a programming language. Learn a programming language or two,
preferably any without angle brackets - C, Perl, Ruby, Java, there is
plenty of choice - and then compare it to XSD. It'll then be clear to
you that XSD is not a programming language.

As with any language, it depends on what use you make of them. Sometimes
it feels like languages are used to create problems.

I'd simply label it "big bubble", or maybe "outer circle", or even
bubblosphere.

I hope this helps!
