You use it like this:
(assuming myModel is the compound property model)
Label idLabel = new Label(idLabel, myModel.bind(id));
This would give component id idLabel, using property id.
CompoundPropertyModel.bind() basically returns a PropertyModel.

If you want to use inheritance:
Put your base form in a panel with the associated markup for the base
fields (making sure there is a wicket:child / tag in the correct
place). Then just extend this panel, adding the required child form
components and supplying the appropriate markup extension
The data you want to show on the page is transient, so it isn't really
bookmarkable.
Use a regular Link and give the page class a constructor that takes your
