		Email,
		r#"
    `email` specifies that the field value must be a valid email address, for
    example "foo@example.com".
    Conforms to the definition for a valid email address from the [HTML standard](https://html.spec.whatwg.org/multipage/input.html#valid-e-mail-address).
    Note that this standard willfully deviates from [RFC 5322](https://datatracker.ietf.org/doc/html/rfc5322),
    which allows many unexpected forms of email addresses and will easily match
    a typographical error.
  "#
	);
	well_known_impl!(
		Hostname,
		r#"
     `hostname` specifies that the field value must be a valid hostname, for
     example "foo.example.com".

     A valid hostname follows the rules below:
     - The name consists of one or more labels, separated by a dot (".").
     - Each label can be 1 to 63 alphanumeric characters.
     - A label can contain hyphens ("-"), but must not start or end with a hyphen.
     - The right-most label must not be digits only.
     - The name can have a trailing dot—for example, "foo.example.com.".
     - The name can be 253 characters at most, excluding the optional trailing dot.
  "#
	);
	well_known_impl!(
		Ip,
		r#"
    `ip` specifies that the field value must be a valid IP (v4 or v6) address.

    IPv4 addresses are expected in the dotted decimal format—for example, "192.168.5.21".
    IPv6 addresses are expected in their text representation—for example, "::1",
    or "2001:0DB8:ABCD:0012::0".

    Both formats are well-defined in the internet standard [RFC 3986](https://datatracker.ietf.org/doc/html/rfc3986).
    Zone identifiers for IPv6 addresses (for example, "fe80::a%en1") are supported.

    "https://example.com/foo/bar?baz=quux#frag".

    URI is defined in the internet standard [RFC 3986](https://datatracker.ietf.org/doc/html/rfc3986).
    Zone Identifiers in IPv6 address literals are supported ([RFC 6874](https://datatracker.ietf.org/doc/html/rfc6874)).
  "#

	well_known_impl!(
		UriRef,

    `uri_ref` specifies that the field value must be a valid URI Reference—either
    a URI such as "https://example.com/foo/bar?baz=quux#frag", or a Relative
    Reference such as "./foo/bar?query".

    URI, URI Reference, and Relative Reference are defined in the internet
    standard [RFC 3986](https://datatracker.ietf.org/doc/html/rfc3986). Zone
    Identifiers in IPv6 address literals are supported ([RFC 6874](https://datatracker.ietf.org/doc/html/rfc6874)).

    The prefix must have all zeros for the unmasked bits. For example,
    "2001:0DB8:ABCD:0012::0/64" designates the left-most 64 bits for the

    `host_and_port` specifies that the field value must be valid host/port
    pair—for example, "example.com:8080".

    The host can be one of:
    - An IPv4 address in dotted decimal format—for example, "192.168.5.21".
    - An IPv6 address enclosed in square brackets—for example, "[2001:0DB8:ABCD:0012::F1]".
    - A hostname—for example, "example.com".

    The port is separated by a colon. It must be non-empty, with a decimal number
    in the range of 0-65535, inclusive.
