The content of element 'ogc:Filter' is not complete (SAXParseException)

[jpassmore2]

Looking at CSW Demo Request page of our GeoNetwork 2.6.4 installation I note that all the example csw-GetRecords | no filter ... examples are generating the following error in the geonetwork.log file when run:

...,861 ERROR [geonetwork.search] - Errors occurred when trying to parse a filter:
...,861 ERROR [geonetwork.search] - ----------------------------------------------
...,861 ERROR [geonetwork.search] - org.xml.sax.SAXParseException: cvc-complex-type.2.4.b: The content of element 'Filter' is not complete. One of '{"http://www.opengis.net/ogc":spatialOps, "http://www.opengis.net/ogc":comparisonOps, "http://www.opengis.net/ogc":logicOps, "http://www.opengis.net/ogc":_Id}' is expected.
...,861 ERROR [geonetwork.search] - ----------------------------------------------

According to OGC, Filter requires children elements but :

• GeoNetwork output the XSD error to the log
• GeoNetwork assumes that the user request for all records and return all results.

<Filter xmlns="http://www.opengis.net/ogc" xmlns:gml="http://www.opengis.net/gml"/>
