Oracle OSB: error: cos-nonambig: Content model violates the unique particle attribution rule.

My team was building schema for the OSB service and SOA-BPM processes and they all are parallely working on the schemas. After completing the schemas we start testing in osb service and process, but in the osb we are getting the following exception:

servicebus:BusinessObjects/Payment/Payment/V1/xsds/PaymentBO.xsd:157:5: error: cos-nonambig: Content model violates the unique particle attribution rule.


So this error occurs at line 157, when I checked the this line I found this:

 <xsd:complexType name="PaymentAuthMod_Type"> -------- line 157
    <xsd:sequence>
      <xsd:element ref="RqUID" minOccurs="0"/>
      <xsd:element ref="AsyncRqUID" minOccurs="0"/>
      <xsd:element ref="CustId" minOccurs="0"/>
      <xsd:element ref="Status" minOccurs="0"/>
      <xsd:element ref="EMVData" minOccurs="0"/>
      <xsd:element ref="NetworkTrnInfo" minOccurs="0"/>
      <xsd:element ref="POSData" minOccurs="0"/>
      <xsd:element ref="PmtAuthRec" minOccurs="0"/>
      <xsd:element ref="PmtAuthId" minOccurs="0" maxOccurs="unbounded"/>
      <xsd:element ref="PmtAuthRec" minOccurs="0" maxOccurs="unbounded"/>
    </xsd:sequence>
  </xsd:complexType>

Solution:

I have gone through some documentation of UPA Rule i.e. Unique Partition Attribution rule which says same element can not have more than one meaning e.g.

<xsd:sequence>
    <xsd:element name="abc" type="xsd:integer" minOccurs="0"/>
    <xsd:any minOccurs="0" maxOccurs="unbounded" />
  </xsd:sequence>

Here, there is one possibility that  xsd:any can be as a element "abc".

OR

<xsd:sequence>
    <xsd:element name="abc" type="xsd:integer" minOccurs="0"/>
    <xsd:element name="abc" minOccurs="0" maxOccurs="unbounded" />

  </xsd:sequence>

So line 157 in my schema there is one element which is repeating with different meaning i.e.

    <xsd:element ref="PmtAuthRec" " minOccurs="0"/>
    <xsd:element ref="PmtAuthRec" minOccurs="0" maxOccurs="unbounded" />

So finally I removed one of the element and it worked.
