+    This schema represents a formalisation of the semantic conditions
+    described in the SKOS eXtension for Labels (SKOS-XL) appendix of the
+    SKOS Reference document dated 18 August 2009, accessible at
+    http://www.w3.org/TR/2009/REC-skos-reference-20090818/#xl. XML comments
+    of the form Sn are used to indicate the semantic conditions that are
+    being expressed. A number of semantic conditions are *not* expressed formally in this schema. These are:
+      S51
+      S55
+      S56
+      S57
+    For the conditions listed above, rdfs:comments are used to indicate the conditions.
