   * providing a structural foundation for the DIDO-TE Concept of Operations and normative requirements.
+===== Relationship to Common Information Types =====
+The DIDO-TE Information Model uses reusable information types defined in [[dido:03-dido-te:05-common-information-types:start|Section 5, Common Information Types]].
+Common Information Types define reusable datatypes, structured types, enumerations, identifiers, names, parameter structures, and other value representations independently of the Information Model classes that use them.
+Information Model class definitions reference those common types rather than redefining their structure or semantics within individual class descriptions.
+This separation allows a common type to be reused consistently by multiple model elements.

-  * Treat the DIDO Reference Data Model as the source for existing modeled elements and relationships.
+  * Treat [DTE4] as the source for existing modeled elements, relationships, attributes, multiplicities, and types.
-  * Do not silently correct anomalies in the source model. Identify corrections or architectural refinements explicitly.
+  * Use Section 5, Common Information Types, for reusable datatype, structured-type, enumeration, identifier, name, parameter, and other common-type definitions.
+  * Do not redefine Common Information Types on Information Model class pages.
+  * Do not silently correct anomalies in [DTE4]. Identify corrections or architectural refinements explicitly.
   * Use focused UML class diagrams for individual model elements before producing the integrated Information Model.
-  * Preserve source-model multiplicities where they are known.
+  * Preserve [DTE4] multiplicities where they are known unless a deliberate DIDO-TE refinement is approved.
-  * Distinguish source-model content from DIDO-TE extensions.
+  * Distinguish [DTE4] source-model content from DIDO-TE extensions.
   * Do not treat UML classes as implementation classes.
   * Develop the Test Definition structure from the constituent model elements and the obligations identified by the DIDO-TE requirements.
-  * Use the integrated diagram in Section 5.14 to show the resulting DIDO-TE Information Model after the individual elements have been reviewed.
+  * Use the integrated diagram in Section 6.14 to show the resulting DIDO-TE Information Model after the individual elements have been reviewed.
