The <cxxUnion> element provides the name of the C++ API union, all the elements necessary to describe the members that are introduced by the union declaration.
The <cxxUnion> element requires an ID attribute as an anchor point; this ID must always be specified. The ID attribute is referenced by the conref attribute and internal applications that refer to the <cxxUnion> element content. The elements <apiName> and <cxxUnionDetail> are required for this top-level container.
