This prevents errors due to nasty typos in the strings. We define all symbols in a single header file that is NOT considered part of the API, as there is no need for MM clients to know about these tags code-wise. These tags are only meaningful when associated to devices in udev. Information of each tag is included in the general API documentation. https://gitlab.freedesktop.org/mobile-broadband/ModemManager/issues/88
