Spec proposal: Editable submissions

As discussed this will be updated so that it now reads:

XForm

  • A new odk:client-editable attribute for the submission node:
    • If the value of odk:client-editable is "true", clients should allow sent submissions to be edited using deprecatedId as a way of linking edits together.
    • If the value of odk:client-editable is anything else, clients should not allow edits after submission (assuming they don't usually).

XLSForm

  • A new client_editable column in the settings sheet whose value will be used to define the new odk:client-editable attribute.
