Issuers can use these notations to add name-value pairs to an OpenPGP signature. -Notation names are UTF-8 encoded strings. They may reside in the "user namespace," which means a notation *tag* (in UTF-8 string format) followed by a DNS domain name. +Notation names – strings encoded in UTF-8 – may reside in the "user namespace." This namespace is characterized by a notation *tag*, followed by a DNS domain name, both in UTF-8 format. -#### Use of notations by Keyoxide - -Notations have, for example, been used for the popular decentralized identity verification service [Keyoxide](https://keyoxide.org/). Keyoxide uses notations in the `ariadne.id` namespace. See the [Keyoxide documentation](https://docs.keyoxide.org/wiki/ariadne-identity/) for more details. +Notations, as described earlier, allow for user-defined extensions to the OpenPGP signature subpacket types. A practical and popular application of this functionality is seen in Keyoxide, a decentralized identity verification service. Keyoxide uses notations in the `ariadne.id` namespace. For the details of this implementation, refer to the [Keyoxide documentation](https://docs.keyoxide.org/wiki/ariadne-identity/). ### "Negotiating" signature hash algorithm based on recipients preference subpackets
