You don't need to convert the std_logic to a std_....

I'm not sure if I'm using "standard" terms, but this is a basic OO question I'm trying to resolve.
I'm coding a windows form. I don't want logic in the form event handler, so I just make a call to a custom object from there.

The whole point of an MVC framework is to separate design (templates) from logic (controllers). However, template languages often afford a limited degree of "design logic" to occur. This includes basic if statements, loops, filtering, etc.

It's just supposed to be devoid of any controller logic.

In that situation where you have very specialized actions happening you need to put it in the logic putting logic relating to this in the Controller is not a sin.

My reasons are fairly simple:
I don't trust the client; this may logic is taking place (I don't have to worry about the Javascript engine available to the client's.

There's nothing wrong with XML for this, but you could save yourself some overhead with a lighter syntax like a LISP-style lists:

The domain is what you something else, physics for instance, there is probably no business logic in your system, but the physics parts are still domain logic.
