think anyone is stupid enough to assert that the phase shift
in a capacitor is the same as it is in the absence of any
physical impedance discontinuity.

Capacitance is not obtained in a physical impedance discontinuity?
or is it:

You missed the point. A terminating capacitor is a two
terminal network. The point where two pieces of feedline
are connected is a four-terminal network. A two-terminal
network is different from a four-terminal network.

Cecil,

This appears to be an unusual definition. How does the "point where two
pieces of feedline are connected" become a four-terminal network? One
typically thinks of a four-terminal network as having inputs and
outputs, with something between. What is that "something between" in the
case of two connected feedlines? In your models this "something" seems
to have no dimensions and no characteristics other than a phase shift.

Are you suggesting that every simple connection is now a four-terminal
network? Do all of the textbooks need to be re-written?
