I just wanted to contribute a tiny bit to the discussion (other than
pointing to the Wiki page that contains some information on code
generation (http://www.nullenvoid.com/mono/wiki/index.php/DeveloperFaq)

A tool like "XSD" would certainly have a use for the CodeDOM, as the
output of this tool is tweakable to generate code in a number of
languages.

But the serializer itself has no need for this when creating the
temporary code for serialization.  In that case, as Atsushi mentions, it
is best to just use WriteLines.

Not advocating a particular implementation strategy for XmlSerializer
just yet.
