[GeoNetwork-users] point representation in Spatial Extent

Hi all,
is there any way to represent point in the Spatial Extent viewbox?
To make it clear for example harvest this SOS service checking the create layers options:http://sensorweb.demo.52north.org/PegelOnlineSOSv2.1/sos?service=SOS&request=GetCapabilities&AcceptVersions=1.0.0

Then you see for the dataset e.g. "Elektrische Leitfähigkeit", the spatial extent is not loaded as it is only represented in point (<gml:boundedBy><gml:Envelope srsName="urn:ogc:def:crs:EPSG::31466"><gml:lowerCorner>5627756.9430557545 2848315.0365082924</gml:lowerCorner><gml:upperCorner>5627756.9430557545 2848315.0365082924</gml:upperCorner></gml:Envelope></gml:boundedBy>).
Does any one know the workaround to support point representation?

Thanks in advanceMani
