Nice. Sounds like this could be the start of a reimplementation of the
Advanced Code Generators (which had been causing many headaches
in the past, see e.g. bugs 84739 and 126262)

Hmm, that's non standard and may upset XMI interoperability.
I suggest using the <codegeneration> in the <XMI.extensions>.
For your example, instead of:

The <UML:SourceCode> would be in the XMI.extensions:

  <codegeneration>
   <codegenerator language="C#" >
    <sourecode id="aHo5uvcmFtyg" value="if (name_ == "TEST") {&#xa;  
return;&#xa;}" />

It may be a little more work (you need to UMLDoc::findObjectById() when
loading the <sourcecode>) but it's the clean way :)

Hope this helps
