Note that associatedOccurrences is one of the several terms that are meant to allow lists of relationships between resources to be captured in a single field. Others include associatedMedia, associatedReferences, associatedSequnces, and associatedTaxa. The main purposes of these fields is to provide a mechanism to share relationship information in a flat application profile such as the Simple Darwin Core (http://rs.tdwg.org/dwc/terms/simple/index.htm). If an application profile isn't constrained by being flat, then there is a much more robust way to capture relationships, using the ResourceRelationship class and it's constituent terms (http://rs.tdwg.org/dwc/terms/index.htm#relindex).
However, the values of the description of the relationship (http://rs.tdwg.org/dwc/terms/index.htm#relationshipOfResource) are not controlled, so this still doesn't provide a "community-defined" vocabulary that Bob was asking about.
