The SubSpecification Component

View Class: View
Spec Class: UISubSpecification

The SubSpecification Component allows inclusion of another specification with all of its components.
The components as defined in the included specification are sliced into the current view. The components bindings are resolved from the current applications bindings (i.e. the aspects of the application are used).

This is in contrast to a subCanvas, which creates an extra subapplication instance, with possibly private aspects.
(i.e. a subCanvas may have its own ApplicationModel providing its own aspects;
whereas a subSpecification only includes another spec)
This is useful to reuse common specifications as a kind of macros.

The Basics Section:

ID	Unique symbolic name (ID) of the box. This ID can be used by the application to access the widget via `"builder>>componentAt:ID"`.
Class	Class which provides the window spec to be included. If left unspecified, the application's class itself is used.
Selector	Message selector sent to the above class, to provide the window spec.
GUI Painter	Opens another GUI Painter on the subSpec.

The Details Section:

Border	Defines the width of the border.
Level	Defines the width of the 3D-border. Positive values provide a raising, negative values provide a lowering of the widget.
