XML editor catalogue entry, xsd:import problem by not resolving the schemaLocation/namespace [message #1734551]

Hi,

Problem:

I am using two EMF models (A and B) which referencing each other. The
WST XML Editor does not resolve the referenced schema (A) as context
assistant for elements of schema A are not provided, only for schema B.

From the two EMF models I export the XSD. There are two XSD files,
where one file references to the other like this:

in schemaB.XSD

<xsd:import namespace="http://xyz.com/schemaA.xsd"
schemaLocation="../../com.xyz.a/model/schemaA.xsd"/>

Both schemas are in different plugins. Each plugin is using the
org.eclipse.wst.xml.core.catalogContributions extension point.

e.g.:
<extension point="org.eclipse.wst.xml.core.catalogContributions">
<catalogContribution id="opn">
<uri name="http://xyz.com/schemaA.xsd" uri="assets/schemaA.xsd"></uri>
</catalogContribution>
</extension>

Workaround:
Please note the ../../ at the schemaLocation of the xsd:import element.
I replaced the ../../ with platform:/plugin/ and this fixed the issue.

Question:
As the namespace http://xyz.com/schemaA.xsd is also at the catalogue I
believe the schema location should be resolved from the catalogue
instead of the schemaLocation attribute at the xsd:import element.

I am wrong or do I misunderstand the catalogue?

Any hints are appreciated, Martin

To whom it may concern,

attached please find 2 plugins for any one who want to reproduce the issue.

Plugin com.xyz.b has a ecore model, schema (b.xsd), etc.

Plugin com.xyz.a has a schema (a.xsd) referencing to x.xsd.

I think all is fine from EMF point of view but after exporting the
product the catalogue entry can't be found by the XML editor.

For me my workaround to replace the schemaLocation in a.xsd will be my
solution to use the WST XML editor.

generated:
[code]
<xsd:import namespace="http://xyz.com/schemaB.xsd"
schemaLocation="../../com.xyz.b/model/b.xsd"/>
[code]

workaround:
[code]
<xsd:import namespace="http://xyz.com/schemaB.xsd" schemaLocation="
platform:/plugin/com.xyz.b/model/b.xsd"/>
[code]

suspected problem:
XML editor does not look into the catalogue to find the schema of the
namespace, but just tries to read the schema from schemLocation.
