                    metadata that is to be included in the document.  The

                    <doc:description>This element contains the additional

                    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").
