Types That Can Be Components
There are certain guidelines to follow when defining types. It is not necessary to
memorize these guidelines because the Type Designer assists you when you
define components. If you drag a type that is not a valid component, the Type
Designer will not let you do it.
Guidelines for Defining Components
The guidelines below are numbered to allow references to the following type tree
and to each other. The numbering does not suggest a priority or a sequence to be
followed in observing the guidelines.
1 Categories may not have components.
A category is only used for organizing your type tree and for setting common
properties.
2 A partitioned group may not have components.
A partitioned group always represents a choice among the sub-types of that
group. You never map a partitioned group without its sub-tree, so it does not
need components.
