All Implemented Interfaces:
XMLStreamReader

Direct Known Subclasses:
ValidatingInfoXMLStreamReader

This class is a wrapper over a generic XMLStreamReader that provides validation. There are 3 cases:
1) the XMLStreamReader represents a document, it contains only one element document - in this case the user schema type should be null or it should be a document SchemaType
2) the XMLStreamReader represents an xml-fragment (content only) - must have at least one user type or xsi:type
a) it has an xsi:type - if user schema type is available it has to be a base type of xsi:type
b) it doesn't have xsi:type - user must provide a schema type otherwise will error and will not do validation
3) the XMLStreamReader represents a global attribute - i.e. user schema type is null and only one attribute
