Please see Section 5.1, "XML Schema Validation and Searching" in the
C++/Tree Mapping Getting Started Guide:

If you have Xerces-C++ built with network support then, yes, schemas
that are specified as URLs will be downloaded. There are also other
methods of specifying schemas to be used for validation, as described
in the document mentioned above.

No, that's not how you do it. Please read Section 5.1 mentioned above
as well as the "XML Schema Part 0: Primer Second Edition", particularly
Section 5.6:

http://www.w3.org/TR/xmlschema-0/

Yes, the generated classes are perfectly usable if you know that the
XML documents you are planning to parse are valid. From Section 5:

"Even when XML Schema validation is disabled, the generated code still
 performs a number of checks to prevent construction of an inconsistent
 object model (for example, an object model with missing required
 attributes or elements)."
