From the content of the IG, it's not clear what the context is where the patient is being judged as being independent or requiring assistance. Does this refer to completing the assessment or daily living or something else. Please clarify the context for this bit of data and clarify why it is only part of the Prior Level profile.

Are the values for "independent" and "assistance-required" a full list of possible values? These values should be part of a value set associated with Extension.value
