If you had to create a type tree that contained numerous infix delimited groups, and numerous unsigned integer elements, what would be the easiest way to create the type tree? Create:

Defining a single group with group and item properties does not provide inheritance to other groups, so each additional infix-delimited group would still require its own property definitions.

Creating a category with the group and item properties lets every subtype within that category automatically inherit the infix delimiter configuration and unsigned integer element settings without redefining them on each individual type. This inheritance mechanism reduces redundant configuration when building numerous similarly structured groups and elements.

Creating separate groups for group properties and item properties increases the number of discrete objects to maintain and provides no shared-property inheritance across the many types that need them.

Defining all groups and elements first and then reorganizing them as category subtypes adds unnecessary rework compared to establishing the category and its shared properties before creating the subtypes.
