troubleshoot JAXB "chameleon schema" Errors

I am trying to use xjc from JAXB 2.1 to generate Java code for the HL7 CDA R2 format. Unfortunately, there appears to be errors in XML Schema files and so xjc fails with this exception.
The XML Schema files can be downloaded from http://xreg2.nist.gov/cda-validation/downloads/archives/HITSP_C37_TestPackage_03Jan_2008.zip, you can also get the Schema files in the attach file.There are total 7 Schema files, and their names are: LabCDA.xsd, LabPOCD_MT000040.xsd, TF_Vol3_Lab.xsd, datatypes.xsd, datatypes-base.xsd, NarrativeBlock.xsd and voc.xsd. The relationship of the Schema files are complex: LabCDA.xsd is the top level Schema and includes LabPOCD_MT000040.xsd; LabPOCD_MT000040.xsd incluedes datatypes.xsd, NarrativeBlock.xsd and voc.xsd and imports TF_Vol3_Lab.xsd; TF_Vol3_Lab.xsd incluedes datatypes.xsd; datatypes.xsd incluedes datatypes-base.xsd; datatypes-base.xsd includes voc.xsd; voc.xsd includes datatypes.xsd. The errors are as follows: [ERROR] A class/interface with the same name "test.jaxb.labreport.cda.ANY" is already in use. Use a class customization to resolve this conflict. line 49 of file:/F:/rcp_workspace/testCreate/processable/coreschemas/datatypes-base.xsd [ERROR] (Relevant to above error) another "ANY" is generated from here. line 49 of file:/F:/rcp_workspace/testCreate/processable/coreschemas/datatypes-base.xsd [ERROR] (Relevant to above error) This confusing error happened most likely because the schema uses a technique called " chameleon schema", which causes a single definition to be loaded multiple times into different namespaces. See http://fo rums.java.net/jive/thread.jspa?threadID=18631 for more about this. line 49 of file:/F:/rcp_workspace/testCreate/processable/coreschemas/datatypes-base.xsd [ERROR] A class/interface with the same name "test.jaxb.labreport.cda.AdxpPostBox" is already in use.
