[oXygen-user] Some more help with interpreting validations errors please

Hi Everyone,

First of all a big thanks to Sorin and George for helping fix my validation
errors that I sent to this list.

Secondly, I have tried to apply my (limited) understanding of those fixes to
the rest of the XML Schema.  I unfortunately can't work through what I think
is a complex structure to work out where I need to add the "import" and
"include" statements.

I have tarred and gzipped the GML and ISO 19139 schema that I am using and
made them available at the following URL:

http://www-test.ga.gov.au/asdd/work/ISO19139GML.tar.gz

I have generated an Oxygen project called smXML.xpr and loaded the following
XML Schema into that project:

Geometry.xsd
TemporalObjects.xsd
applicationSchema.xsd       bad
basicTypes.xsd
citation.xsd                bad
constraints.xsd
content.xsd                 bad
dataQuality.xsd             bad
distribution.xsd            bad
extent.xsd                  bad
generalFeatureModel.xsd
identification.xsd          bad
maintenance.xsd             bad
metadataApplication.xsd     bad
metadataEntity.xsd          bad
metadataExtension.xsd       bad
portrayalCatalogue.xsd      bad
referenceSystem.xsd         bad
scXMLbase.xsd
spatialRepresentation.xsd   bad

I have also noted which files do not *individually* validate by putting the
word "bad" next to the above file list.  The Geometry.xsd validates
individually.  However, if I validate some XML Schema that "import"
Geometry.xsd then Geometry.xsd has the following errors:

"http://www.w3.org/TR/xmlschema-1/#src-resolve	E src-resolve: Cannot resolve
the name 'gml:AbstractGeometryType' to a(n) 'type definition' component.
Geometry.xsd	file:/E:/downloads/ISO19139/2004-08-17/ssXML/Geometry.xsd
37:80"

"http://www.w3.org/TR/xmlschema-1/#src-resolve	E src-resolve: Cannot resolve
the name 'gml:AbstractGeometricPrimitiveType' to a(n) 'type definition'
component.	Geometry.xsd
file:/E:/downloads/ISO19139/2004-08-17/ssXML/Geometry.xsd	27:39"

"http://www.w3.org/TR/xmlschema-1/#src-resolve	E src-resolve: Cannot resolve
the name 'gml:PointType' to a(n) 'type definition' component.	Geometry.xsd
file:/E:/downloads/ISO19139/2004-08-17/ssXML/Geometry.xsd	16:91"

"http://www.w3.org/TR/xmlschema-1/#src-resolve	E src-resolve: Cannot resolve
the name 'gml:Point' to a(n) 'element declaration' component.	Geometry.xsd
file:/E:/downloads/ISO19139/2004-08-17/ssXML/Geometry.xsd	20:44"

"http://www.w3.org/TR/xmlschema-1/#src-resolve	E src-resolve: Cannot resolve
the name 'gml:_GeometricPrimitive' to a(n) 'element declaration' component.
Geometry.xsd	file:/E:/downloads/ISO19139/2004-08-17/ssXML/Geometry.xsd
31:58"

"http://www.w3.org/TR/xmlschema-1/#src-resolve	E src-resolve: Cannot resolve
the name 'gml:_Geometry' to a(n) 'element declaration' component.
Geometry.xsd	file:/E:/downloads/ISO19139/2004-08-17/ssXML/Geometry.xsd
41:48"


Similarly, if I validate TemporalObjects.xsd there are no errors yet if I
validate XML Schema in the project then those XML Schema that "import"
TemporalObjects.xsd indicate that TemporalObjects.xsd has the following
errors:

"http://www.w3.org/TR/xmlschema-1/#src-resolve	E src-resolve: Cannot resolve
the name 'gml:AbstractTimeObjectType' to a(n) 'type definition' component.
TemporalObjects.xsd
file:/E:/downloads/ISO19139/2004-08-17/stXML/TemporalObjects.xsd
23:65"

"http://www.w3.org/TR/xmlschema-1/#src-resolve	E src-resolve: Cannot resolve
the name 'gml:AbstractTimePrimitiveType' to a(n) 'type definition' component.
TemporalObjects.xsd
file:/E:/downloads/ISO19139/2004-08-17/stXML/TemporalObjects.xsd
13:38"

"http://www.w3.org/TR/xmlschema-1/#src-resolve	E src-resolve: Cannot resolve
the name 'gml:_TimePrimitive' to a(n) 'element declaration' component.
TemporalObjects.xsd
file:/E:/downloads/ISO19139/2004-08-17/stXML/TemporalObjects.xsd
17:53"

"http://www.w3.org/TR/xmlschema-1/#src-resolve	E src-resolve: Cannot resolve
the name 'gml:_TimeObject' to a(n) 'element declaration' component.
TemporalObjects.xsd
file:/E:/downloads/ISO19139/2004-08-17/stXML/TemporalObjects.xsd
27:50"


I believe that the problem has something to do with the link between the
ISO19139 XML Schema files and the GML XML Schema files.  I have somehow come
to this conclusion because of the following commonly occurring validation
error:

"E src-resolve: Cannot resolve the name 'gml:......' to a(n) 'type
definition' component."

Please note that the "......" represents different  GML types and elements.


"E src-resolve: Cannot resolve the name 'gml:AbstractTimeObjectType' to a(n)
'type definition' component.	TemporalObjects.xsd
file:/E:/downloads/ISO19139/2004-08-17/stXML/TemporalObjects.xsd
23:65"

How can a file be valid and also invalid?  Can anyone help me track down
which files need the "import" or "include" statements?

Thanks.
