One possibility is to change the short description very slightly:
Current
Use a <learningObjectMap>
to create standalone aggregations of <learningContent>
together with its supporting plan, overview, summary, and
assessments, according to the needs identified by the learning
goals and objectives. The <learningObjectMap>
references one and only one <learningObject>.
Any <topicref> elements
that occur before the <learningObject>
are intended to be resource-only references such as key
definitions.
Revised
Use a <learningObjectMap>
to create standalone aggregations of <learningContent>
together with its supporting plan, overview, summary, and
assessments, according to the needs identified by the learning
goals and objectives. Use a <learningObjectMap>
to reference a single <learningObject>.
Any <topicref> elements
that occur before the <learningObject>
are intended to be resource-only references such as key
definitions.
