In an attempt to isolate XSDs from WSDLs such that we have one and only one
Maven module containing XSDs I have run into the following problem when running
cxf-codegen-plugin from a module separated from the XSD module:

{code}
If the XSDs are located within the *same* project that is running
cxf-codegen-plugin, everything works fine. It's only when the XSDs are being
referenced from the classpath that this problem occures.
The error above originates when parsing FICR_IN110304CA.xsd, it references a
schema named FICR_MT510401.xsd and within that schema (on line 105) there is an
xs:group element like so:
{{<xs:group ref="InfrastructureRootElements"/>}}
InfrastructureRootElements is supposed to be imported via the statement on line
86 of that same schema:
{{<xs:include schemaLocation="../coreschemas/infrastructureRoot.xsd"/>}}
I've attached a sample project which replicates the problem. unzip the project
and execute a {{mvn clean install}} within the CXFSchemaRefProblemPom directory.
I've also attached a variables view of the schema references loaded at runtime
from my IDE when this error occures. The reference to infrastructureRoot.xsd
looks to be proper to me.
