Bug 4208: identifiers should use WSDL 1.1 element names not WSDL 2.0 component names

>From http://www.w3.org/Bugs/Public/show_bug.cgi?id=4208

The WSDL 1.1 EI specification uses "In" and "Out" for message
references. 
These are currently used because that is what WSDL 2.0 defines in it's
component designators.  However, "In" and "Out" are WSDL 2.0 message
labels,
generated from the "input" and "output" element information items.  

WSDL 1.1 uses "input" and "output" as the element names, and WSDL 1.1
EIs
should use those as messageReferences.

Proposal: 

Replace In with input and replace Out with output in WSDL 1.1 EI spec.

Cheers,
Dave
