Feature request: enumeration values in default request comments

I develop web services and use SoapUI regularly for regression testing.  I also recommend SoapUI to application developers so they can form the request they want before implementing it in their programming framework.  This also means I often give a short introduction to using SoapUI.  One of the parts which is difficult to explain is where to find valid enumeration values when a field has a restriction.  I usually get them to look at the 'WSDL content' or to look through the documentation.  However, it is not always easy to find if the WSDL imports a number of schema files or the documentation is large/hard to find.  The Validate function also only gives you a negative error message - to say that the value is not valid, but doesn't say what *is* valid.  Maybe i've missed an easier route?

Therefore, I believe having an XML comment which says something like would be very useful in front of enumeration fields.
