Permit to validate only selected objects binded with [BindProperty] for use with different forms in a single RazorPage

[tmm360]

How is well described in this question https://stackoverflow.com/questions/48516547/how-to-implement-two-forms-with-separate-bindproperties-in-razor-pages would be useful to be able to have different input models with different bindings for each form in a single RazorPage.

Currently ModelState property validate all models together, but for each form is desirable that only related model is validated. Otherwise having others unmanaged models will lead to have ModelState.IsValid == false for each request asking for validation.

Is your feature request related to a problem? Please describe.

I'm trying to validate only selected binded models when I execute a query on a RazorPage having different forms and different binded models.

Describe the solution you'd like

I'd like to have a simple way for validate only selected models, something like ModelState.IsValid(MyBindedProperty).

I believe that can have multi forms in a single page is a fundamental feature for RazorPage.
