Answer 1

You could write an XSLT to do something like that. But the problem is, a single document alone is not enough information to generate a schema. Are any of those elements optional? Is there anything missing from that document, that might appear in other instances? How many of a particular element can there be? Do they have to be in that order? There are loads of things that can be expressed in a schema, that are not immediately obvious from one instance of a document that conforms to that schema.
