You can display the domain of an attribute in the symbol of an entity. There are four display options available:

Data types Domains	Displays both data type and domain, if they exist
Data types Replace by domains	If domain exists and data type does not exist, then displays domain. If domain does not exist and data type exists, then displays data type.
