+Form controls should support submission and validation through the following conventions by implementing the `ShoelaceFormControl` interface:
 
-- All form controls must use `name`, `value`, and `disabled` properties in the same manner as `HTMLInputElement`
-- All form controls must have a `setCustomValidity()` method so the user can set a custom validation message
-- All form controls must have a `reportValidity()` method that report their validity during form submission
-- All form controls must have an `invalid` property that reflects their validity
+- All form controls must use `name`, `value`, `disabled`, etc. in the same manner as `HTMLInputElement`
+- All form controls must implement `checkValidity()`, `reportValidity()`, `setCustomValidity()`, etc. for validation
 - All form controls should mirror their native validation attributes such as `required`, `pattern`, `minlength`, `maxlength`, etc. when possible
 - All form controls must be tested to work with the standard `<form>` element
