If a ResourceShape has multiple values for oslc:describes (it constrains more than one class, often things that might be subtypes of some abstract supertype), ReSpec only lists the last entry in the list in the Name, URI and table heading fields.
See the TRS specification, then ChangeEvent shape for an example. This shape constrains three vocabulary items: trs:Creation, trs:Modification and trs:Deletion. Only Deletion is listed in the generated HTML.
