Error consuming external webservice: <elements> violate "Unique Particle Attribution"

When I try to create a web service descriptor from a WSDL in Designer 9.6 for IS 8.2.2, I get this error:

The issue is that some of the complex elements in the WSDL have named elements followed by “any” elements. For example:

	<xsd:element name="objectReferentId" type="common:ObjectIdentifierType" nillable="true" minOccurs="0" maxOccurs="1"/>
	<xsd:element name="additionalRowInfo" type="AdditionalInfoType" nillable="true" minOccurs="0" maxOccurs="1"/>
	<xsd:any minOccurs="0" maxOccurs="unbounded"/>

SOAPUI handles this WSDL without complaint. Is there anything I can do to convince webMethods to do the same?

I submitted this question to SAG support also and got this response:

After following these instructions I was able to generate the WSD.
