4.5 Allowed Location

A value of this type represents an allowed location for a member in an XML representation – some members (e.g., the xml:lang Directive defined in 5.3.13) may only be specified as attributes in XML, and not as member elements; some (e.g. the x:Items member defined in 5.3.1) may not appear in XML at all, and are only used in a Xaml Information Set. Values of this type are one of: Any, AttributeOnly, or None.
