The "When is it a soundtrack / when is it classical?" question

Related to this is how do others know what guidelines you are following. For example the guidelines for classical releases are quite different to the vanilla Rock/Pop standards for (track/recording) artists but how do you know which guidelines the editor has used. I feel there should be at least be some flag saying this release is considered classical has been entered according to the classical guidelines as opposed to a classical release that has been added using the vanilla guidelines. Without such a flag how is the data to be interpreted, especially if the interpretation is being done by computer rather than human.
