Try searching for level on the page you linked, it is listed, along with syntax. I think its name is the only practical explanation of its meaning, as I mentioned, it can be completely different for each codec.

The thing is, if you need to produce output in a certain profile or level, more often than not you will know the constraints imposed or more likely, you don’t care/have no choice because it is mandated by the limitations in the consumer of the output. Also the tables & definitions for levels covers 7 pages for h264.
