As things get better with C++ modules, it may now be useful to add support for the ixx module extension. Unlike a typical translation unit, there is no header separation for writing the documentation. This means that we must either A: write the documentation inline in the module, or B: write the documentation off-source in .dox files. Whichever choice we make, the module extension, just like the headers previously used, must be parsed by doxygen.
