        note: |
          The value SHOULD be normalized to lowercase.

          Consider always setting the transport when setting a port number, since
          a port number is ambiguous without knowing the transport, for example
          different processes could be listening on TCP port 12345 and UDP port 12345.

          `network.protocol.version` refers to the version of the protocol used and might be
          different from the protocol client's version. If the HTTP client used has a version
          of `0.27.2`, but sends HTTP version `1.1`, this attribute should be set to `1.1`.
