      Description

      The following code segment demonstrates parsing a schema and then serializing with xmlUtil. xmlUtil, in it's attempt to discard necessary namespaces, is discarding namespaces that are actually needed.

      Save the original schema and the referenced schema in eclipse, and there will be no errors. Save the output schema (as MyRevSchema.xsd for example) and you'll have errors as a result of the dropped namespaces.

      import groovy.xml.*
      
      scSrc = '''<?xml version="1.0" encoding="UTF-8"?>
      <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
          attributeFormDefault="unqualified" elementFormDefault="qualified"
          targetNamespace="urn:cargal.net/myNS" xmlns="urn:cargal.net/myNS"
          xmlns:myns="urn:cargal.net/myNS">
          <xsd:include schemaLocation="MyRefSchema.xsd" />
          <xsd:complexType name="myCT2">
              <xsd:complexContent>
                  <xsd:extension base="myns:myCT">
                      <xsd:sequence>
                          <xsd:element name="element1" />
                      </xsd:sequence>
                  </xsd:extension>
              </xsd:complexContent>
          </xsd:complexType>
          <xsd:element name="test" type="myns:myCT" />
          <xsd:element name="test2" substitutionGroup="subG" type="myCT2" />
      </xsd:schema>
      '''
      
      schema = new XmlSlurper().parseText(scSrc)
      println schema.lookupNamespace('')
      println schema.lookupNamespace('myns')
      println new XmlUtil().serialize(schema)
      

      results:

      urn:cargal.net/myNS
      urn:cargal.net/myNS
      <?xml version="1.0" encoding="UTF-8"?><xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" attributeFormDefault="unqualified" elementFormDefault="qualified" targetNamespace="urn:cargal.net/myNS">
