[XML-SIG] Help writing out xml

[Harry George]

An option is to write the xml manually.   That is, each object in your
"model" (as in model-view-controller) has a "to_xml" method which takes
a fileobject (sys.stdout is default), and writes itself in XML to
that file.   

Indents are controlled by some formatting mechanism.  I
personally use my "tabbedwriter":

I've done this with a lot of XML's and find it is easy to control and
trivial to setup.   Where there is inheritance in the "model", a lot of
the XML output can be done by the base object(s).
