/**
* Type declaration AST node type. A type declaration
* is the union of a class declaration and an interface declaration.
* For JLS2:
* <pre>
* TypeDeclaration:
* ClassDeclaration
* InterfaceDeclaration
* ClassDeclaration:
* [ Javadoc ] { Modifier } <b>class</b> Identifier
* [ <b>extends</b> Type]
* [ <b>implements</b> Type { <b>,</b> Type } ]
* <b>{</b> { ClassBodyDeclaration | <b>;</b> } <b>}</b>
* InterfaceDeclaration:
* [ Javadoc ] { Modifier } <b>interface</b> Identifier
* [ <b>extends</b> Type { <b>,</b> Type } ]
* <b>{</b> { InterfaceBodyDeclaration | <b>;</b> } <b>}</b>
* </pre>
* For JLS3, type parameters and reified modifiers
* (and annotations) were added, and the superclass type name and superinterface
* types names are generalized to type so that parameterized types can be
* referenced:
* <pre>
* TypeDeclaration:
* ClassDeclaration
* InterfaceDeclaration
* ClassDeclaration:
* [ Javadoc ] { ExtendedModifier } <b>class</b> Identifier
* [ <b><</b> TypeParameter { <b>,</b> TypeParameter } <b>></b> ]
* [ <b>extends</b> Type ]
* [ <b>implements</b> Type { <b>,</b> Type } ]
* <b>{</b> { ClassBodyDeclaration | <b>;</b> } <b>}</b>
* InterfaceDeclaration:
* [ Javadoc ] { ExtendedModifier } <b>interface</b> Identifier
* [ <b><</b> TypeParameter { <b>,</b> TypeParameter } <b>></b> ]
* [ <b>extends</b> Type { <b>,</b> Type } ]
* <b>{</b> { InterfaceBodyDeclaration | <b>;</b> } <b>}</b>
* </pre>
* <p>
* When a Javadoc comment is present, the source
* range begins with the first character of the "/**" comment delimiter.
* When there is no Javadoc comment, the source range begins with the first
* character of the first modifier or annotation (if any), or the
* first character of the "class" or "interface" keyword (if no
* modifiers or annotations). The source range extends through the last character of the "}"
* token following the body declarations.
* </p>
