Title:  OWS Common change request: add schemalocation for XML namespace

Source:  Peter Schut, WPS RWG

Work item code:  Date:  2007-10-22

Category:  F

Use one of the following categories:

F (Critical correction)

A (corresponds to a correction in an earlier release)

B (Addition of feature),

C (Functional modification of feature)

D (Editorial modification)

Detailed explanations of the above categories can be found in the TC Policies and Procedures.

Reason for change:  The current OWS Common ExceptionReport.xsd schema references an obsolete version of the XML schema, and therefore does not validate properly if an XML validator actually attempts to import the XML schema at this obsolete location. As a consequence other OGC schemas cannot import the exception report schema.

This validation problem exists in the XML validators that the OGC has

standardized on to schemas (xerces-j and xsv). It does not occur in the latest (v2008) XMLSpy, although it occurs in the 2006 version.

Summary of change:  In

ows/1.1.0/owsExceptionReport.xsd replace

<import namespace="http://www.w3.org/XML/1998/namespace"/> with

Consequences if 

not approved: XML schema validation with xerces-j and xsv will fail for WPS and other OGC standards which attempt to use the Exception Report portion of OWS Common.

Potential for OGC standards to look poor.
