[jQuery] [validation] How to pop current rules for given input and how to set them back?


In some cases I need not to validate some fields. E.g. If I check some
checkbox new inputs with further options are shown. These inputs
should be validated when submitting form. If I uncheck the checkbox no
options are needed and they disappear (they should not be validated).
It's clear.
My problem is how to remove them from validation. I could remove the
rules on "change" on the checkbox, but I don't know the rules on
inputs because they are generated. So is it possible to remove somehow
the rules (when unchecking the checkbox) and set them back again
(after checking the checkbox).
E.g.
inputRules = jQuery("#someInput").rules(); // gets the rules
jQuery("#someInput).rules("remove"); // and removes the rest (the
two rows are equal to "pop")
//but how to put them back?
jQuery("#someInput).rules("add", inputRules); // "sets" the rules
Is it possible somehow?
