In theory we can have some JS script that can be usable in client AND

Considering that the object model are very different in the form and in the client, that seems difficult to me.
However what I'd like to see is to reuse the validation rules in the form-definition. Implementing "assert" is much more difficult. As Sylvain wrote, should be quite simple to implement three kinds of validations: check on field presence, basic format checks and a custom function.
This should cover the 90% of user requirements.
We need this feature soon, so I've thinked to write a transformer that
enrich the form instance with javascript functions (Decorator Pattern)
and can be placed in the pipeline just before the final XSL.
Please consider my proposal of having validators output an XML fragment that is later transformed to JS by the presentation stylesheets. It would just require to upgrade the XSLs.
