The PascalCase feature in 3.5 beta is great! However, if the tag name contains periods, the root element name generated is incorrect. It sets element name with an XmlRootAttribute constructor parameter ("T.1.01.0") and ElementName ("T1010"), but ElementName is not the tag name but the class name. See below for an example.
