Schema Compliance Assertion failing with error "Invalid xsi:type qname:'b:boolean' in element"

SOAPUI 5.0.0:

We are adding Schema Compliance assertion as a part of automation standard.

For some methods, the Schema Compliance assertion is failing with error "Invalid xsi:type qname:'b:boolean' in element" elementnameType@http://schemas.microsoft.com/2003/10/Serialization/Arrays"

Please help me to resolve this issue.

Thanks,
