As part of the refactor to the node declaration builders, we had hoped to add a regular expression specifically for these socket names, but recent discussions have revealed that using the translation marker macros is the preferred solution. If the names and descriptions were exposed to RNA, these would not be necessary. However, that may be quite complicated, since sockets are all instances of the same RNA types.
