Thank you for the feedback.  I've putt additional comments inline:

6DOF will have implications for people who are quadripalegic and for people
that use a wheelchair / mobility aid for navigation. In this case we are
concerned about moving directionally in physical space and I think has a
higher emphasis on the lower extremity for movement.

3DOF will have implications for people who have motor impairments that
affect the use of one or both arms.

I meant section 4. XR User Needs and Requirements. I see you have 4.19
about Subtitling Customization but I don't see a previous Requirement about
having Captions as a starting point.

Makes sense to me.  I think there is additional work to build a navigation
UI that is separate from having an annotation UI for objects. I'll try to
share some real world examples from VR experiences soon.
