WebForms 2: can you set willValidate attribute?

[FataL]

Can I set willValidate attribute to false to prevent validation of form field or form itself?
Specification is not very clear enough about this:

• Opera doesn't get attention to willValidate attribute set to false -- it wants to validate fields anyway. See my disscussion with Hallvord Steen from Opera about issue.
• JavaScript implementation of Web Forms 2 by Weston Ruter will not validate fields with willValidate attribute set to false.

P.S. Here is some tests for this issue.

Update: I found in specs that willValidate is read only.
But this is brings another question: how to remove validation from some form fields?

What is the use case?

Real world example:
I have form with repetition template for members (name, e-mail, phone, etc.). Some fields in fieldset are required -- such name and e-mail.
By default there is only one empty fieldset for one member, but more can be added via "Add another member" template button.
Also, if user leaves all fields in member fieldset blank, there should be no required fields for completly empty fieldset.

Another example from real world:
I have a form where some fields are required depends on what user entered in other fields, so under some circumstances some fields transforms from required to optional.

Code: Select all

Age: <input type=number name=age min=1><br>
If you are from 18 to 21 y.o.:<br>
Question 1: <input type=text name=q1 required>
Question 2: <input type=text name=q2>
<br>
If you are 22 and up:<br>
Question 1: <input type=text name=q1 required>
Question 2: <input type=text name=q2 required>
Question 3: <input type=text name=q2 required>

Third example (similar to previous one):
I have multiple options that implemented via radio buttons. When some options were choosen, they provide additional fields to fill out (required or optional).
I need a way to say to a browser to not validate all fields that not attached to selected option.

Code: Select all

<input type=radio name=a> Option 1<br>
Additional info: <input type=text name=aa required>

<input type=radio name=a> Option 2<br>
Additional info 1: <input type=text name=bb>
Additional info 2: <input type=text name=cc required>

<input type=radio name=a> Option 3<br>
Additional info 1: <input type=text name=dd required>
Additional info 1: <input type=text name=ee required>

<input type=radio name=a> Option 4

Just set .required = false;
