If a serialization/reparsing does help, then I would suspect some
namespace
related issued in the original node-tree; but this is just a vague guess
without looking at you screen.

- Check if the namespace-URI (doc->node->ns) of the document-element
  is correct; check if the declared namespaces (doc->node->nsDef) are
  correct.
- Check if you have correctly built a schema at all; there might be
  a chance that you validate with an empty schema.
  1) xmlSchemaNewParserCtxt(), xmlSchemaNewDocParserCtxt(), ...
  2) xmlSchemaParse()
  3) xmlSchemaNewValidCtxt()
  4) xmlSchemaValidateDoc()
