[GS to GN] Generated MDs via "CSW-T Insert" / gco XML prefix issue

[pmauduit]

When creating MD via CSW-T, even if the root element for each MD contains a reference to the gco prefix, this one is discarded from the root element, and repeated on each element which needs it, e.g.:

  <gmd:contact>
    <gmd:CI_ResponsibleParty>
      <gmd:individualName>
        <gco:CharacterString xmlns:gco="http://www.isotc211.org/2005/gco">Maël REBOUX - Service Information Géographique</gco:CharacterString>
      </gmd:individualName>
[...]

Yet perfeclty valid XML, this is not very human-readable (well, if we can consider human-readablility of iso19139 metadatas ...). One solution will be to force gco to be defined on each root element of inserted metadatas, here is a unit test which validates this approach:

    @Test
    public void testXmlSerializationGcoEachElem() throws IOException, JDOMException {
        Element elem = Xml.loadStream(this.getClass().getResourceAsStream("mdgco-eachelem.xml"));
        elem.addNamespaceDeclaration(Namespaces.GCO);
        assertTrue(Xml.getString(elem).contains("<gmd:MD_Metadata xmlns:gmd=\"http://www.isotc211.org/2005/gmd\" xmlns:geonet=\"http://www.fao.org/geonetwork\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:gco=\"http://www.isotc211.org/2005/gco\" xsi:schemaLocation=\"http://www.isotc211.org/2005/gmd http://www.isotc211.org/2005/gmd/gmd.xsd http://www.isotc211.org/2005/gmx http://www.isotc211.org/2005/gmx/gmx.xsd http://www.isotc211.org/2005/srv http://schemas.opengis.net/iso/19139/20060504/srv/srv.xsd\">"));
    }

To be placed somewhere in the CSW-T code and the Metadata's dataManager GN logic.
