What does it means? "compiler was unable to honor this property customization. It is attached to a wrong place, or its inconsistent with other bindings."

Hello all!!

Im getting an error while trying to bind a XML schema to a Java. The XML
schema is the DocBook 4.5 XML Schema that you can get in
http://www.docbook.org/xsd/4.5/

The next is the xjc version im using:

raul_at_sensei:~/docbook/schema/xsd/4.5$ xjc.sh -version
xjc version "2.1.3-b01-fcs"
JavaTM Architecture for XML Binding(JAXB) Reference Implementation, (build
2.1.3-b01-fcs)
from package jaxb-ri-20070413

and java -version:
raul_at_sensei:~/docbook/schema/xsd/4.5$ java -version
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode, sharing)

When I try to parse the schema I get the a lot of errors (you can see the
complete output errors below) :

raul_at_sensei:~/docbook/schema/xsd/4.5$ xjc.sh -d /home/raul/ -p DocBook
docbook.xsd

Im interested in two of them cause I could solve others with jaxb
customizations.

Theses are the lines about the error in dbhierx.xsd

  1728 
  1729 <xs:element name="indexentry">
  1730 <xs:complexType>
  1731 <xs:sequence>

  1745 </xs:sequence>
  1746 <xs:attributeGroup ref="indexentry.attlist"/>
  1747 </xs:complexType>
  1748 </xs:element>

I' ve tried to use a customized binding as next:

(custom3.xjb)

<jxb:bindings version="1.0"
  xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
  jxb:extensionBindingPrefixes="xjc">
    <jxb:bindings schemaLocation="dbhierx.xsd" node="/xs:schema">
        <jxb:bindings
node="//xs:sequence[@minOccurs='0']//xs:choice/xs:element[@ref='seeie']">
            <jxb:property name="E1ASeeie"/>
        </jxb:bindings>
    </jxb:bindings>
</jxb:bindings>

However I get the next error (cutted for readability):

raul_at_sensei:~/docbook/schema/xsd/4.5$ xjc.sh -d /home/raul/ -p DocBook
docbook.xsd -b custom3.xjb
parsing a schema...
[ERROR] compiler was unable to honor this property customization. It is

  line 8 of file:/home/raul/docbook/schema/xsd/4.5/custom3.xjb

[ERROR] (the above customization is attached to the following location in
the schema)
  line 1740 of file:/home/raul/docbook/schema/xsd/4.5/dbhierx.xsd

[ERROR] Element "seeie" shows up in more than one properties.
  line 1737 of file:/home/raul/docbook/schema/xsd/4.5/dbhierx.xsd

[ERROR] The following location is relevant to the above error
  line 1733 of file:/home/raul/docbook/schema/xsd/4.5/dbhierx.xsd

I tried to use:
<jxb:class name="E1ASeeie"/> instead of

<jxb:property name="E1ASeeie"/>

but I get the same error.

I tried with xjc 2.0 version provided with java1.6 but similar errors are
reported.

So, Is there any customization to address this problem? �What exactly means
"compiler was unable to honor this property customization. It is attached to
a wrong place, or its inconsistent with other bindings."?

Thanks in advance,

Raul.
