No, that really isn't it. I've confirmed that if I have:

   This part is normal. '''This part is bold.'''

The method that invokes the strong highlighting *really*is* called
before the method that prints the text:

  -- formatter.strong is called to open
  -- formatter.strong is called to close
  -- formatter.rawtext (one I added) is called with "This part is
normal. This part is bold."

You see, I don't actually print the text as I go. In order to make sure
I produce proper XML, nothing is actually printed until
formatter.endDocument.

It seems that upon further investigation of the source code, the parser
is calling the formatter on strong tags and then *inserting* whatever it
returns into the text, before calling formatter.rawtext -- although this
answers my question, it doesn't really solve my problem.

I'm asking for advice on what the best way to build a document using
DOM. This process doesn't seem to fit into the formatter method because
of the problem I describe above.
