Yes, this was exactly the intention.  And some of the discussions around the issue use the term "born binary" to mean schemas that are encoded into a processor, with no "external" XML representation ever actually having existed.

Typically XML Schema syntax in XML (though I gather there are some experiments out there with alternative syntaxes).

The schema processor.

They can.  As a convenience a processor can build-in the schema components of a given namespace such that the user need not have to supply an external expression of those schema components.

I don't know any that do, just because I haven't looked, but it is certainly possible for a processor to offer this.

I hope this helps.
