Please don't take my previous response to mean you shouldn't post your
comments questions, they are quite relevant and appropriate. More below.

Please do continue with additional questions/comments!

In Sanjiva's pseudo-schema mark-up, the @body attribute is optional.
Basically, anything inside square brackets '[' is optional, with choice 
denoted by multiple values separated by a pipe '|'.


<operation name="ncname">
    <input [body="qname"|element="qname"] [headers="list-of-qnames"]/>
    <output [body="qname"|element="qname"] [headers="list-of-qnames"]/>

The @body and @element attributes are optional, with there being a further
constraint that either @body or @element may appear in an <input> or 

Note that the @header attribute is also optional in this pseudo-schema.
