B. WSDL definitions can share the same XML schema and can also link to multiple XML schemas, so stating that 4 SOAP-based Web services must have 4 XML schemas is incorrect.
C. Each WSDL definition must have at least 2 XML schemas, so the correct amount of required XML schemas in this case is 8.
D. There is nothing wrong with this statement.

Identify what is wrong with this statement: "SOAP-based Web services A and B are participating in a runtime transaction that is carried out as per the WS-AtomicTransaction standard. When a message sent by Service A is rejected by Service B due to a violation of a WS-Policy definition expressed as part of the Service B contract, Service A is forced to issue an Abort message, thereby requiring the transaction to be rolled back." Select the correct answer.
A. WS-AtomicTransaction does not support the rollback of changes that occur during runtime transactions.
B. WS-Policy definitions are not expressed as part of the service contract.
C. SOAP-based Web services cannot have policies and cannot participate in runtime transactions because they are limited to the use of a uniform service contract.
D. There is nothing wrong with this statement.
