This interface represents an assembly document and does not contain any methods. Intended for later use.
Note
You can use it to check what kind of document you have. In MS Visual C++, calling this interface with method QueryInterface(...) from a document returns NULL which means that this document isn't an assembly document. The same thing can be done in MS Visual Basic using the Set method. Assigning to a variable declared as IAssemblyDocument type with the Set method a variable of the IDocument type, returns an error if there is no assembly document.
