        Get the typed value of a node that is annotated with this schema type. This method must be called only for a valid type.
        Specified by:
        getTypedValue in interface SchemaType
        Parameters:
        node - the node whose typed value is required

        Specified by:
        atomize in interface SchemaType
        Parameters:
        node - the node whose typed value is required

        Specified by:
        isSameType in interface SchemaType
        Parameters:
        other - the other type
        Returns:

        public java.lang.String getDescription()
        Description copied from interface: SchemaType

        getDescription in interface SchemaType
        Returns:
        text identifing the type, for use in a phrase such as "the type XXXX".

        Parameters:
        value - the input string to be checked
        nsResolver - a namespace resolver used to resolve namespace prefixes if the type is namespace sensitive. The value supplied may be null; in this case any namespace-sensitive content will throw an UnsupportedOperationException.
        nameChecker - XML 1.0 or 1.1 name checker, for types such as xs:NCName
        Returns:
        null if validation succeeds; return a ValidationFailure describing the validation failure if validation fails. Note that the exception is returned rather than being thrown.
        Throws:
        java.lang.UnsupportedOperationException - if the type is namespace-sensitive and no namespace resolver is supplied

        Throws:
        ValidationException - if the supplied value is not in the lexical space of the data type
