+The HED `DataProperty` entities map an entity (Domain) into a value (Range) as
+specified by the `Domain` and `Range` fields.
+The `heds:HED_0000005` ID is the `HedTag` class.
+In the HED schema, the domain and range of a schema attribute are 
+conveyed by the schema properties,
+which are also given as annotation properties.
+The `hed:HED_0010704 true` annotation corresponds to the `tagDomain` schema property being true, 
+while the `hed:HED_0010702 true` annotation corresponds to the `boolRange` schema property being true.
+
+Similarly, the HED `ObjectProperty` entities map an entity (Domain) into another entity (Range)
+specified by the `Domain` and `Range` fields as illustrated in the following example:
+
+````{admonition} **Example** HED Manchester OWL syntax for rooted.
+```text
+bjectProperty: hed:HED_0010106
+	Annotations:
+		dc:description "A tag that is often associated with this tag. This attribute is used by tagging tools to provide tagging suggestions.",
+		rdfs:label "suggestedTag",
+		hed:HED_0010704 true,
+		hed:HED_0010705 true
+	Domain:
+		hed:HED_0000005
+	Range:
+		hed:HED_0000005
+```
+````
+
+The `heds:HED_0000005` ID is the `HedTag` class, indicating that `suggestedTag`
+maps one HED tag into another. 
+The `hed:HED_0010704 true` and `hed:HED_0010705 true` provide this information as annotations.
+
+
 Unlike `DataProperty` and `ObjectProperty` attributes, `AnnotationProperty` attributes 
 are not inherited and do not use domain and range specifications.
 These must be handled individual by tools as flagged by the HED schema `annotationProperty` property.
