GMLWriter is using the wrong namespace

[GoogleCodeExporter]

The GMLWriter is using urn:gml as namespace for GML instead of the correct 
http://www.opengis.net/gml.

"The OGC has developed a URN structure and a set specific URNs..."
As example this gml looks valid
http://irmaservices.nps.gov/unit/geography/list/ROMO,GLAC/ConvexHull/GML 

have you some additional info?

The wikipedia link you refer to has to do with CRS URN's, which are a way of 
telling the reader of the GML which coordinate system the coordinates are in.
My problem has to do with the actual XML namespace of the GML nodes.
When the GML writer writes a GML node it uses 'xmlns:gml="urn:gml"' for the 
namespace, where I would like it to use 
'xmlns:gml="http://www.opengis.net/gml"'.

When I look at JTS implementation, I can see that they also use 
http://www.opengis.net/gml:
http://jts-topo-suite.svn.sourceforge.net/viewvc/jts-topo-suite/tags/Version_1.1
2/jts/java/src/com/vividsolutions/jts/io/gml2/GMLConstants.java?revision=628&vie
w=markup

But no so, when looking at the equivalent NTS file GMLElements:

O/GML2/GMLElements.cs

can you check your code using trunk rev 844?
