Type properties
The properties of a type define the characteristics of the data objects of that type.
For item types, properties define whether that item is text, a number, a date and time, or a syntax value. Properties include such characteristics as size, pad characters, and justification.
For group types, the properties are related to the format of that group. The format of a group may be explicit or implicit. In addition, type properties include syntax objects that appear at the beginning or end of the object, as well as release characters.
