 @name ngRepeat:iidexp
 @fullName Invalid Identifier
 @description
+
+Occurs when there is an error in the identifier part of {@link api/ng.directive:ngRepeat ngRepeat}'s expression.
+
+To resolve, use either a valid identifier or a tuple (_key_, _value_) where both _key_ and _value_ are valid identifiers.
+
+Examples of *invalid* syntax:
+
+```
+<div ng-repeat="33 in users"></div>
+<div ng-repeat="someFn() in users"></div>
+<div ng-repeat="some user in users"></div>
+```
+
+Examples of *valid* syntax:
+
+```
+<div ng-repeat="user in users"></div>
+<div ng-repeat="(id, user) in userMap"></div>
+```
+
+Please consult the api documentation of {@link api/ng.directive:ngRepeat ngRepeat} to learn more about valid syntax.
