+                    metadata to be included in the document.  This element
+                    should be used for extending EML to include metadata
+                    that is not already available in another part of the EML
+                    specification, or to include site- or system-specific
+                    extensions that are needed beyond the core metadata.  The
+                    additional metadata contained in this field describes the
+                    element referenced in the 'describes' element preceding it.
+                    The content of this field is any well-formed XML fragment.
+                    If that content contains namespace declarations, and if
+                    the namespace declaration can be resolved to a schema
+                    defniition, then the content will be validated against
+                    that schema definition.  If no namespace is present,
+                    or if no schema can be resolved, validation for this
+                    fragment will be skipped (validation is "lax").
