Mukul Gandhi commented on XERCESJ-1577:
---------------------------------------
Here are the results I've observed on the xml-schema-1.1-dev branch,
main.xsd
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";
elementFormDefault="qualified" targetNamespace="mainNS" xmlns:ns="mainNS">
<xs:include schemaLocation="test.xsd"/>
</xs:schema>
test.xsd
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";
elementFormDefault="qualified">
<xs:element name="elem" substitutionGroup="p.trans"/>
<xs:element name="p.trans" abstract="true"/>
</xs:schema>
When I use the jaxp.SourceValidator sample to check the schema document
main.xsd as follows,
jaxp.SourceValidator -a main.xsd I do get the error you've mentioned
But when I invoke this sample as following (an option, -f is "full schema
checking" enabled),
jaxp.SourceValidator -a -f main.xsd (XSD 1.0 mode)
or
jaxp.SourceValidator -a -f -xsd11 main.xsd (XSD 1.1 mode)
I don't get the error you've mentioned.
You may validate these findings, and report if you don't agree. I suspect,
you're not initializing the "schema factory" or/and the Schema object with all
the right options (you may look at the source code of jaxp.SourceValidator to
see, that what all options are needed).

> Key: XERCESJ-1577
> URL: https://issues.apache.org/jira/browse/XERCESJ-1577
> Project: Xerces2-J
> Issue Type: Bug
> Components: XML Schema 1.0 Structures
> Affects Versions: 2.11.0
> Reporter: Radu Coravu
>
> Tested with the libraries from the Xerces-J 2.11.0-xml-schema-1.1-beta
> release.
> If I have a small schema in no-namespace like:
> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";
> elementFormDefault="qualified">
> <xs:element name="elem" substitutionGroup="p.trans"/>
> <xs:element name="p.trans" abstract="true"/>
> </xs:schema>
> and a schema which has a target namespaces and includes it:
> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";
> elementFormDefault="qualified" targetNamespace="mainNS" xmlns:ns="mainNS">
> <xs:include schemaLocation="test.xsd"/>
> </xs:schema>
> Validation of the main schema (or of an XML referencing the XML schema)
> reports the following problem:
> src-resolve.4.1: Error resolving component 'p.trans'. It was detected that
> 'p.trans' has no namespace, but components with no target namespace are not
> referenceable from schema document
> 'file:/C:/Users/radu_coravu/Desktop/xsdProblem/test.xsd'. If 'p.trans' is
> intended to have a namespace, perhaps a prefix needs to be provided. If it is
> intended that 'p.trans' has no namespace, then an 'import' without a
> "namespace" attribute should be added to
> 'file:/C:/Users/radu_coravu/Desktop/xsdProblem/test.xsd'.
> Basically the reference to a substitution group which is in a chameleon
> schema is not properly binded once the schema is included from a schema which
> has a target namespace.
> This worked in Xerces 2.9.1.
