[jira] Commented: (XERCESJ-1112) The parser do no support multiple
inclusions of the same "sub"-schema
[ http://issues.apache.org/jira/browse/XERCESJ-1112?page=comments#action_12363444 ]
James Coughlin commented on XERCESJ-1112:
-----------------------------------------
I too have a simular problem:
[Error] DWIrmcCommon.xsd:16:27: sch-props-correct.2: A schema cannot contain two global components with the same name; this schema contains two occurrences of 'irmc,grp_SysID'.
My schema directory implementation is thus:
DW1/Schemas/CCD
Schemas folder contains files:
DW_BaseTypes.xsd
DW_Debtor.xsd
DW_IRMC_Common.xsd
CCD folder contains files:
DWDebtor.xsd
DWIrmcCommon.xsd
The xml instance document's xsi:schemaLocation attribute:
<DebtorFile
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xsi:schemaLocation="irmc http://jackflash/DW1/Schemas/CCD/DWDebtor.xsd"
xmlns="irmc"
>
I am attaching a zip file containing the schema files, this file will be called DW1.zip
I would agree that there is some "fishy" here.
The .NET 2.0 Microsoft validating parser has no problem or errors with this schema and the <refefine> feature.

> Key: XERCESJ-1112
> URL: http://issues.apache.org/jira/browse/XERCESJ-1112
> Project: Xerces2-J
> Type: Bug
> Components: XML Schema Structures
> Versions: 2.7.1
> Environment: Any platform. Problem exists on any version of Xerces
> Reporter: Jean-Jacques Thomasson
> Assignee: Sandy Gao
> Attachments: ParseWithXerces.zip, bugXercesStudy.zip, dm.zip, dmodule_descriptSchema_flat.xsd
>
> An example :
> In a schema named "complexTypes.xsd", we define the following inclusions :
> <xs:include schemaLocation="attributeGroups.xsd"/>
> <xs:include schemaLocation="simpleElements.xsd"/>
> <xs:include schemaLocation="complexElements.xsd"/>
> <xs:include schemaLocation="elementGroups.xsd"/>
> and, in "complexEelements.xsd", we use the following inclusions :
> <xs:include schemaLocation="complexTypes.xsd"/>
> (Since we need element definitions to define complexTypes and vice-versa).
> Most of the parsers (XSV, XMLSpy) are now supporting this kind of self-mirroring inclusions which is admitted by the W3C recommendation (Note 2 of section 4.2.1 "Schema Representation Constraint: Inclusion Constraints and Semantics ").
> But Xerces produces (a series of) the following sample message :
> "[Error] complexTypes.xsd:32:54: sch-props-correct.2: A schema cannot contain two global components with the same name; this schema contains two occurrences of ',contentType_fn3dktizrknc9pi'."
> It is an important matter of concern for industries wishinig to have a complex architecture of schemas such as the aeerospace industry.
> Please, could you look at this ?
