A domain can only be deleted if no feature or sensors are member of that domain. Note that this also applies to deleted (but not purged) features. Deleting a domain will also delete all subordinate domains.
For the deleted domain as well as for all subordinate domains following related data is also deleted:
•Alias Schemes
•Approval Templates
•Assigned Coordinate Systems
•Attachment Tag Aliases
•Axes
•Classifications
•Cross Section Outlines
•Used classification association
•Feature creation templates
•Feature Subtypes
•Hidden Feature Types
•Map file sets
•Presentation templates (Chart, Map view, Report, Axis Section Drawing)
•Privileges
•Property structure configurations
•Stored export definitions
•Stored import definitions
•View - Domain associations
If the domain to be deleted is used as the default domain focus in a user's profile the domain focus will be deleted from that user's profile
