If I really want to designate portions of a net that need to be separated by some PWB feature, I draw them as separate nets and then connect them with a "part" that is used to connect them in the layout. For example, I have a part which can use the same voltage for I/Os that it uses for the core Vcc. But a different version of the part uses a much lower core Vcc. So the two Vccs are separate nets and I use a jumper symbol to connect them. In layout I have a choice of how to implement that jumper, as a two pin header, a zero ohm resistor or a two pin device that is nothing but a PWB copper connection between the two pins.
How would you make use of "subnets" that would be useful that you can't do with just nets?

Otherwise, certain nets (such as power or ground nets), which often have vastly different characteristics in different sections, would be difficult to describe.
