Defines a set of annotations that can be used on TypedXmlWriter interfaces.

## Package-level Annotation

{@link XmlNamespace} can be used on a package to designate the namespace URI for the whole package.

## Interface Annotation

{@link XmlElement} can be used on TypedXmlWriter-derived interfaces to associate a tag name to that interface.

## Method Annotations

{@link XmlElement}, {@link XmlAttribute}, or {@link XmlValue} can be used on a method declared on a TypedXmLWriter-derived interface. Those annotations are mutually-exclusive. See their javadoc for details. If none of the above three annotations are specified, {@link XmlElement} is assumed.
