No, XSD does not provide built-in support for this. Rather, you would
need to do it at the Xerces-C++ DOM level. That is, first read the XML
to DOM, verify the signature, then parse DOM to object model. Similarly,
for serialization, first serialize the object model to DOM, add the
signature, then serialize DOM to XML.

You can use the Apache XML Security Library for C++ to do all the
signing/verifying:
