editorial: rephrase definition of the 204 No Content status code
to be (hopefully) clearer about server expectations rather than a
SHOULD requirement on a specific UI.

    1400    The server has successfully fulfilled the request, but there is no
    1401    additional content to return in the response payload body.  The
    1402    resource metadata and representation metadata in the response message's
    1403    header fields refer to the target resource
    1404    and its current representation, respectively, after the requested action.
     1400   The 204 (No Content) status code indicates that the server has
     1401   successfully fulfilled the request and that there is no additional
     1402   content to return in the response payload body.  Metadata in the
     1403   response header fields refer to the target resource and its current
     1404   representation after the requested action.
     1405</t>
     1406<t>
    14051407   For example, if a 204 status code is received in response to a PUT
    1406    and the response contains an ETag header field, then the value of
    1407    that field is the current entity-tag for the representation that
    1408    was successfully PUT.
    1409 </t>
    1410 <t>
    1411    If the client is a user agent, it &SHOULD-NOT; change its document view
    1412    from that which caused the request to be sent. This response is
    1413    primarily intended to allow input for actions to take place without
    1414    causing a change to the user agent's active document view, although
    1415    any new or updated metadata &SHOULD; be applied to the document
    1416    currently in the user agent's active view.
     1408   request and the response contains an ETag header field, then the PUT
     1409   was successful and the ETag field-value contains the entity-tag for
     1410   the new representation of that target resource.
     1411</t>
     1412<t>
     1413   The 204 response allows a server to indicate that the action has been
     1414   successfully applied to the target resource while implying that the
     1415   user agent &SHOULD-NOT; traverse away from its current "document view"
     1416   (if any).  The server assumes that the user agent will provide some
     1417   indication of the success to its user, in accord with its own interface,
     1418   and apply any new or updated metadata in the response to the active
     1419   representation.
     1420   For example, a 204 status code is commonly used with document editing
     1421   interfaces corresponding to a "save" action, such that the document
     1422   being saved remains available to the user for editing. It is also
     1423   frequently used with interfaces that expect automated data transfers
     1424   to be prevalent, such as within distributed version control systems.
