So I'm planing my next build, a Goddard and Townsend inspired tea table. In looking at some pictures of surviving examples, I've noted the cabriole legs appear to terminate at the knee. The picture attached shows the aprons appear mitered above the knee and not mortised into the leg such as most casework I've seen is.

Anyone have a guess how the leg is attached to the aprons?
