target = "https://www.rfc-editor.org/rfc/rfc9000#section-22.1.3" # 22.1.3. Reclaiming Provisional Codepoints # # A request might be made to remove an unused provisional registration # from the registry to reclaim space in a registry, or a portion of the # registry (such as the 64-16383 range for codepoints that use # variable-length encodings). This SHOULD be done only for the # codepoints with the earliest recorded date, and entries that have # been updated less than a year prior SHOULD NOT be reclaimed. # # A request to remove a codepoint MUST be reviewed by the designated # experts. The experts MUST attempt to determine whether the codepoint # is still in use. Experts are advised to contact the listed contacts # for the registration, plus as wide a set of protocol implementers as # possible in order to determine whether any use of the codepoint is # known. The experts are also advised to allow at least four weeks for # responses. # # If any use of the codepoints is identified by this search or a # request to update the registration is made, the codepoint MUST NOT be # reclaimed. Instead, the date on the registration is updated. A note # might be added for the registration recording relevant information # that was learned. # # If no use of the codepoint was identified and no request was made to # update the registration, the codepoint MAY be removed from the # registry. # # This review and consultation process also applies to requests to # change a provisional registration into a permanent registration, # except that the goal is not to determine whether there is no use of # the codepoint but to determine that the registration is an accurate # representation of any deployed usage.
