| | | Thanks to everyone for the info. Now that I'm reading the spec, I have a question (and may have more later). In one part, it lists three conditions that must be met in order for BFC clipping to occur. The last condition is the following: 4 - No (...) (22 years ago, 12-Mar-03, to lugnet.cad.dev)

More accurately, it means 'turn off clipping until/unless it gets turned back on in this file, overriding any possibility of clipping in a subfile, until the end of this (...)

So a subfile won't be BFC'd unless all its parents are certified and it is certified as well. Also, presumably if you refer to a subfile in a section (...)
