When you are testing a Web Service using Web Services Explorer, you might encounter this error:
"IWAB0380E Errors were encountered while validating XML schemas"
However, the message erroneously points to a wsdl file that has no validation error.
This is an error emitted by Microsoft® Internet Explorer™ which uses the XSD parser to read XSD type documents. Since the XSD parser has no knowledge of WSDL, the parser does not know how to handle in-line schemas in the WSDL file.
Microsoft Internet Explorer has custom code that works around this error, thus the error is harmless and can be treated as such.
