core/schema/component.model: _isResetOnRevisit missing

[danielghost]

The _isResetOnRevisit attribute doesn't seem to be exposed within the Authoring Tool. Is there a reason for this?

The need to set this at a component level is fairly uncommon, but it can be required. For example, when question responses are restored across sessions via _shouldStoreResponses, you may wish to disable this for particular questions or only restore responses for passed assessments and therefore need to override this via _isResetOnRevisit on the relevant components.

We should allow true, false, "soft" and "hard" values.

Is there a reason for this?

I'm sure I asked this same question recently but I can't find any reference to that now!
