Limitations

Interwiki links (e.g. w:) are not supported. Neither do fragments (e.g. #Foo).

An interwiki title cannot be resolved completely, since there is no way to know what the other wiki’s namespace configurations are.

A title is supposed to represent an “address” or a “path”, not the real page. That said, the fragment is not considered a part of a title. However, the parser will strip out the fragment part, if any.

Note that Title.fragments returns something entirely different: a list of strings created by splitting the title by /.
