Metadata storage and XLink resolution

Metadata stored in DB:

<gmd:contact>
<gmd:CI_ResponsibleParty xlink:href= »xml/codelist/CI_ReponsibleParty.xml#xpointer(//gmd:CI_ResponsibleParty[id='XXXX'])xmlns(gml=http://www.isotc211.org/2005/gmd) »/></gmd:contact>
<gmd:contact>

Metadata after XLink resolver operation:

		<gmd:CI_ResponsibleParty xlink:href= »xml/codelist/CI_ReponsibleParty.xml#xpointer(//gmd:CI_ResponsibleParty[id='XXXX'])xmlns(gml=http://www.isotc211.org/2005/gmd) »>
			<gmd:individualName gco:nilReason="missing">
				<gco:CharacterString/>
			</gmd:individualName>
			<gmd:organisationName>
                                    ...
		</gmd:CI_ResponsibleParty>
