Layer with filter using href not working

[matax87]

I am not able to define a layer using a filter to check if a property coded in a xml href attribute is a certain literal.

<FeatureLayer>
    <FeatureType>ps:ProtectedSite</FeatureType>
    <Filter>
      <ogc:Filter>
        <ogc:PropertyIsEqualTo>
          <ogc:PropertyName>ps:siteDesignation/ps:DesignationType/ps:designationScheme/@xlink:href</ogc:PropertyName>
          <ogc:Literal>http://inspire.ec.europa.eu/codelist/DesignationSchemeValue/UNESCOManAndBiosphereProgramme</ogc:Literal>
        </ogc:PropertyIsEqualTo>
      </ogc:Filter>
    </Filter>
    <l:Name>PS.ProtectedSitesUNESCOManAndBiosphereProgramme</l:Name>
    <d:Title>Protected Sites - UNESCO Man and Biosphere Programme</d:Title>
    <s:CRS>EPSG:3035</s:CRS>
    <l:StyleRef>
      <l:StyleStoreId>PS_ProtectedSite_Default</l:StyleStoreId>
      <l:Style>
        <l:StyleName>PS.ProtectedSite.Default</l:StyleName>
        <l:LayerNameRef>PS.ProtectedSites</l:LayerNameRef>
        <l:StyleNameRef>PS.ProtectedSite.Default</l:StyleNameRef>
      </l:Style>
    </l:StyleRef>
  </FeatureLayer>
</FeatureLayers>

I found that the problem is in the MappedXPath.java class, see the attached trace log:

@MrSnyder I think the problem is related to org.deegree.feature.persistence.sql.xpath.MappedXPath
