    1676       </p>
    1677       <p id="rfc.section.5.2.1.p.2">HTTP status codes are generic; that is, they are potentially applicable to any resource, not just one particular media type,

     3211      <p id="rfc.section.11.2.2.p.1">When it is necessary to express new semantics for a HTTP response that aren't specific to a single application or media type,
     3212         and currently defined status codes are inadequate, a new status code can be registered.
     3213      </p>
     3214      <p id="rfc.section.11.2.2.p.2">HTTP status codes are generic; that is, they are potentially applicable to any resource, not just one particular media type,
     3215         "type" of resource, or application. As such, it is preferred that new HTTP status codes be registered in a document that isn't
     3216         specific to a single application, so that this is clear.
     3217      </p>
     3218      <p id="rfc.section.11.2.2.p.3">Definitions of new HTTP status codes typically explain the request conditions that produce a response containing the status
     3219         code (e.g., combinations of request header fields and/or method(s)), along with any interactions with response header fields
     3220         (e.g., those that are required, those that modify the semantics of the response).
     3221      </p>
     3222      <p id="rfc.section.11.2.2.p.4">New HTTP status codes are required to fall under one of the categories defined in <a href="#status.codes" title="Response Status Codes">Section&nbsp;5</a>. To allow existing parsers to properly handle them, new status codes cannot disallow a response body, although they can mandate
     3223         a zero-length response body. They can require the presence of one or more particular HTTP response header field(s).
     3224      </p>
     3225      <p id="rfc.section.11.2.2.p.5">Likewise, their definitions can specify that caches are allowed to use heuristics to determine their freshness (see <a href="#Part6" id="rfc.xref.Part6.19"><cite title="HTTP/1.1, part 6: Caching">[Part6]</cite></a>; by default, it is not allowed), and can define how to determine the resource which they carry a representation for (see <a href="#identifying.response.associated.with.representation" title="Identifying the Resource Associated with a Representation">Section&nbsp;8.1</a>; by default, it is anonymous).

    1244   The HTTP Status Code Registry defines the name space for the status-code

    1248   Values to be added to this name space require IETF Review

    1255 <section title="Considerations for New Status Codes" anchor="considerations.for.new.status.codes">
    1256 <t>
    1257    When it is necessary to express new semantics for a HTTP response that
    1258    aren't specific to a single application or media type, and currently defined
    1259    status codes are inadequate, a new status code can be registered.
    1260 </t>
    1261 <t>
    1262    HTTP status codes are generic; that is, they are potentially applicable to
    1263    any resource, not just one particular media type, "type" of resource, or
    1264    application. As such, it is preferred that new HTTP status codes be
    1265    registered in a document that isn't specific to a single application, so
    1266    that this is clear.
    1267 </t>
    1268 <t>
    1269    Definitions of new HTTP status codes typically explain the request
    1270    conditions that produce a response containing the status code (e.g.,

     4080   When it is necessary to express new semantics for a HTTP response that
     4081   aren't specific to a single application or media type, and currently defined
     4082   status codes are inadequate, a new status code can be registered.
     4083</t>
     4084<t>
     4085   HTTP status codes are generic; that is, they are potentially applicable to
     4086   any resource, not just one particular media type, "type" of resource, or
     4087   application. As such, it is preferred that new HTTP status codes be
     4088   registered in a document that isn't specific to a single application, so
     4089   that this is clear.
