First cut at a LearningResource definition.

The actual definitions are commented out to give LRMI folk a chance to review
rather than be surprised with this showing up in the Web.

+    <span property="rdfs:comment">The LearningResource type can be used to indicate things (e.g. a [[CreativeWork]], [[Event]], [[Product]] etc.) that have
+a particular and explicit orientation towards learning, education, skill acquisition and other educational purposes.
+
+[[LearningResource]] is expected to be used as an addition to a primary type such as [[Book]], [[Video]] etc.
+
+Every [[EducationEvent]] is a [[LearningResource]], and the various outcomes from such events might or might not be usefully considered to also be [[LearningResource]]s.
+For example, an [[EducationEvent]] might have associated [[CreativeWork]]s that are [[recordedIn]] the event or are a [[workFeatured]] or [[workPerformed]] of the event.
+Similarly, the (proposed) [[CourseInstance]] type represents as an [[Event]] an occurrence of a [[Course]]; we consider anything that is one of these types to
+by definition be a [[LearningResource]].
+
+It should be also noted that there is currently no consensus in the wider schema.org community as to whether a [[LearningResource]] type is useful, or whether it would
+be better modeled purely as a subtype of [[CreativeWork]].
