Corrections for test-suite

While working on Woden milestone 4, I discovered three good tests in the 
test suite (that I contributed) that are actually invalid. All three 
contain the following snippet:

<wsdl:input element="xs:string" />
<wsdl:output element="xs:string" />

This is invalid as xs:string is not an element. (This violates assertion 
Schema-0020.)

I've attached a patch that corrects the three good test cases. 

Arthur - Please review and apply the patch to correct these tests.



Thanks,

Lawrence Mandel
