These allow for the introduction of additional document elements, and their renderings, on top of those provided by DocBook. For example, some of the teams at my company wanted features in the final Word document that amounted to arbitrary Word field-code support in the SGML. To support this, I wrote a local DocBook stylesheet and definition file pair (Local.DSL, Local.DTD) to emit the sequences in RTF corresponding to t...

See questions 4.2, 4.19 and in particular 6.22 in the Python FAQ for more on this topic.) The base class is B; this one's easy. Since B is a class, its type is ``class''; so the type of the base class is the type ``class''. This is also known as types.ClassType, assuming the standard module types has been imported. Now is the type ``class'' callable? No, beca...
