I'm replying to my own message after a short discussion on IRC with
Stephan Richter, for anybody which would be interested in the answer...

The problem is coming from the ITestSkin interface, which was inheriting
from IDivFormLayer : actually, IDivFormLayer benefit is to provide a
ready to use div-based form layout ; so if your goal (like for me in
this example) is just to override this layout template, inheriting from
IDivFormLayer doesn't make any sense.

Problem was finally solved with the following statements :

    class ITestSkin(z3c.formui.interfaces.IFormUILayer,ITestLayer):
        ...

    <z3c:template
        for="z3c.form.interfaces.IInputForm"
        template="mydiv-form.pt"
        layer=".ITestLayer" />


Many thanks,
Thierry
