[wfs-dev] GML 2.1.2 and XMLSpy

[Simon.Cox@csiro.au]

There are various schema validation issues with all versions of GML
prior to 3.1.1. 
This was consistent with industry norms for schemas of this level of
complexity, 
since XML processing technology was immature at the time of development.

Only in the last couple of years have they all started to agree - in the
case of Xerces C++ only in the past couple of months! 

GML3 was adopted by OGC in January 2003 and there are no plans to bugfix
GML2.

Hi list,

when trying to validate WMC 1.0 documents with Altova XMLSpy I always 
run into the following error in geometry.xsd from GML 2.1.2:

File 
D:\svn\mapbuilder\mapbuilder\mapbuilder\demo\data\context\atlasWorld.xml

could not be validated because of an error in XML Schema/DTD (see below)
    File http://schemas.opengis.net/gml/2.1.2/geometry.xsd is not valid.
        Type 'gml:MultiPolygonType' is not a valid restriction of type 
'gml:GeometryCollectionType'.

Is there a solution to this?

Thanks in advance.
