        description "A type representing an SCCP address in string form.
                    The basic form of an SCCP address is:

                    `type=<variant>,ri=<address type>,<parameter>=<value>,...`

                    where `<variant>` is `A7` for ANSI-variant SCCP or `C7` for ITU-variant SCCP,
                    and `<address type>` is one of `gt` or `pcssn`
                    (for an address specified by Global Title (GT),
                    or Point Code (PC) and Subsystem Number (SSN), respectively).

                    The `<parameter>` options are:

                    - Point code: `pc=<point code in network-cluster-member (ANSI)
                    or integer (ITU) format>`
                    - Subsystem number: `ssn=<subsystem number 0-255>`
                    - Global title address digits: `digits=<address digits, one or more 0-9>`
                    - Nature of address: `nature=<nature>` where `<nature>` is
                    `unknown`, `international`, `national`, or `subscriber`
                    - Numbering plan: `numbering=<numbering>` where `<numbering>` is
                    `unknown`, `isdn`, `generic`, `data`, `telex`, `maritime-mobile`,
                    `land-mobile`, `isdn-mobile`, or `private`
                    - Global title translation type: `tt=<integer 0-255>`
                    - National indicator: `national=<true or false>`.

                    `parameter` names are separated from their values by an equals sign,
                    and all `<parameter>=<value>` pairs are separated by commas.
                    Do not include any whitespace anywhere in the address.

                    Only the `ssn` and `national` parameters are mandatory; the others are optional,
                    depending on the details of the address - see below.

                    Note carefully the following:

                    - For ANSI addresses, ALWAYS specify `national=true`,
                    unless using ITU-format addresses in an ANSI-variant network.
                    - For ITU addresses, ALWAYS specify `national=false`.
                    - All SCCP addresses across the deployment's configuration
                    must use the same variant (`A7` or `C7`).
                    - Be sure to update the SGC's SCCP variant in `sgc-config.yaml`
                    to match the variant of the addresses.

                    ---

                    For PC/SSN addresses (with `ri=pcssn`), you need to specify
                    the point code and SSN.
                    For GT addresses (with `ri=gt`), you must specify the global title digits
                    and SSN in addition to the fields listed below (choose one option).

                    There are two options for ANSI GT addresses:

                    - translation type only
                    - numbering plan and translation type.

                    There are four options for ITU GT addresses:

                    - nature of address only
                    - translation type only
                    - numbering plan and translation type
                    - nature of address with either or both of numbering plan and translation type.

                    ---

                    Some valid ANSI address examples are:

                    - `type=A7,ri=pcssn,pc=0-0-5,ssn=147,national=true`
                    - `type=A7,ri=gt,ssn=146,tt=8,digits=12012223333,national=true`

                    Some valid ITU address examples are:

                    - `type=C7,ri=pcssn,pc=1434,ssn=147,national=false`
                    - `type=C7,ri=gt,ssn=146,nature=INTERNATIONAL,numbering=ISDN,tt=0,
                    digits=123456,national=false`
                    - `type=C7,ri=gt,ssn=148,numbering=ISDN,tt=0,digits=0778899,national=false`";
