@SchemaValidation annotation does not work if schemaLocation property is not specified

Steps to reproduce:
1. Create simpe JAX-WS service
2. Annotate it with @SchemaValidation annotation WITHOUT specifying optional schemaLocation property (In such case schema should be extracted from the WSDL)
3. Send test request

As the result no schema validation is performed and you will see the following messages in log:

17:07:13,421 INFO [SOAPBodyElementDoc] Validating: DOM_VALID
17:07:13,421 WARN [SchemaExtractor] Cannot find element:

{http://schemas.xmlsoap.org/wsdl/}

types

17:07:14,515 WARN [SchemaExtractor] Cannot find element:

types

The problem root is that org.jboss.ws.extensions.validation.SchemaExtractor class could not load 'types' element from WSDL as this element does not present in WSDL directly but imported via 'import' element.
