How to inform xjc not to go through xs:import?

Question

I want to create a java classes from the xsd using xjc ant task. Most of it works ok. I need it not to go through and because it already has mapping done. Here is xsd:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema targetNamespace="urn:oasis:names:tc:opendocument:xmlns:digitalsignature:1.0"
   xmlns:xs="http://www.w3.org/2001/XMLSchema"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:dsig="urn:oasis:names:tc:opendocument:xmlns:digitalsignature:1.0"
   xmlns:xmldsig="http://www.w3.org/2000/09/xmldsig#" 
   xmlns:xades="http://uri.etsi.org/01903/v1.3.2#" 
   elementFormDefault="qualified"
  >
    <xs:import namespace="http://www.w3.org/2000/09/xmldsig#" 
       schemaLocation="http://www.w3.org/TR/2002/REC-xmldsig-core-20020212/xmldsig-core-schema.xsd" />
    <xs:import namespace="http://uri.etsi.org/01903/v1.3.2#" 
       schemaLocation="http://uri.etsi.org/01903/v1.3.2/XAdES.xsd" />
    <xs:import namespace="http://uri.etsi.org/01903/v1.4.1#" 
       schemaLocation="http://uri.etsi.org/01903/v1.4.1/XAdESv141.xsd" />
    <xs:element name="document-signatures">
        <xs:complexType>
            <xs:sequence minOccurs="1" maxOccurs="unbounded">
                <xs:element ref="xmldsig:Signature" />
            </xs:sequence>
        </xs:complexType>
    </xs:element>
 </xs:schema>

xjc goes through all imports and creates binding classes. But I already have those. So how to inform xjc to use already created bindings in the classpath? For xades implementation I'll use xades4j library

Thanks,

You can use episode files to do modular schema compilation:
