C# code generation templating help

[Thom]

I'm a newbie to using visio to generate code. I'm looking at the template for
creating classes from UML diagrams and can't find any details of the
templating language sytnax or macros I can use to customize the code
generated.

I was hoping to be able to do something sort of like:

if <class == 'xxx' > then <insert this code in template> else <insert other
code> etc.

but I'm unsure how flexible the code generation template is.

Is the code generation template syntax documented anywhere?
I've found references to customizing the basic graphical templates, but,
alas, nothing for the code-gen templates.

Can anyone provide a helping hand here?

Thanks,

Thom
