Ok. But that didn't really answer my question. When should
maxwidth:physical be used? Does this have to be signposted? Measured? What
exactly does it describe? When should one use it and when should width or
maxwidth be used?


So when should maxwidth:physical be used? One example I can think of might

What about maxwidth:physical in this example?
