Non-MTOM Part Replaced with XOP Indlude Tag

Hi Team,

I have the following schema definition and sample XML payload. When the property child is not included in a <list> element, the property node value will be replaced with XOP Include element. The resultant XML payload will fail in schema validation for those non-MTOM parts. I am using soapUI pro 4.5.0.1. Is this a soapUI bug or schema definition issue? However, the WSDL/XSD schema are WS-I compliant. Please advise.

Sample Payload:

Properties Schema Definition:

<xs:element name="properties" minOccurs="0" maxOccurs="1">
<xs:complexType>
<xs:sequence>
<xs:element name="property" minOccurs="0" maxOccurs="unbounded">
<xs:complexType mixed="true">
<xs:sequence minOccurs="0" maxOccurs="1">
<xs:element type="xs:string" name="list" maxOccurs="unbounded" minOccurs="0"/>
</xs:sequence>
<xs:attribute type="xs:string" name="name" use="required"/>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
Content Schema Definition:
<xs:element name="contentElements" minOccurs="0" maxOccurs="1">
<xs:complexType>
<xs:sequence>
<xs:element name="contentElement" minOccurs="1" maxOccurs="unbounded">
<xs:complexType>
<xs:sequence>
<xs:element type="xs:string" name="fileName" minOccurs="1" maxOccurs="1"/>
<xs:element name="content" type="dm:imageData" minOccurs="1" maxOccurs="1"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>

<xs:simpleType name="imageData" xmime:expectedContentTypes="application/octet-stream">
<xs:restriction base="xs:base64Binary"/>
</xs:simpleType>
