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.
