The sec_rgy_attr_sch_lookup_by_id( ) call reads the attribute schema entry identified by UUID. The output of the call is a sec_attr_schema_entry_t type that contains the specified attribute type's name, UUID, and characteristics. Generally, this call is used for programmatic access.
For interactive access, use the sec_rgy_attr_sch_lookup_by_name( ) call. This call returns the same information as the sec_rgy_attr_sch_lookup_by_id( ) call but specifies the schema entry to read by name instead of by UUID.
