Issue 195: slightly updated simple proposal

 Hi all, 8-)
 this is the first part of my former proposal [1], updated a 
little and standing on its own so it's not so confusing.
 In short, the update removes the mandatory presence or absence
of the return value in the struct representation, it adds a note
about the array representation, and it does some rephrasing in
places.
 The proposal:

 It needs to be clarified that in the array representation of RPC
result the return value is not named rpc:result (because as we
cannot specify positions in structs, we cannot specify names in
arrays). Therefore I propose the fifth bullet to be changed to:

 * The response is viewed as a single struct or array containing
an outbound edge for the return value and each [out] or [in/out]
parameter. If the response is an array, the return value edge
MUST be the first edge in the array.

 And the sixth bullet in the RPC Body section - 4.1 [1] - should
be split into:

 * Each outbound edge has a label corresponding to the name of
the parameter (see A Mapping Application Defined Name to XML
Name) or a position corresponding to the position of the
parameter. 

 * In the struct representation of the response, the label of the
return value outbound edge is "result" and it is
namespace-qualified with the namespace name
"http://www.w3.org/2001/12/soap-rpc".

 * In the array representation of the response, the return value
outbound edge is the first member of the array if the return
value of the procedure is non-void. If the return value of the
procedure is void, the first edge is the first [out] or [in/out]
parameter.
 Note: in case the application designers only know the format of
the messages, they are free to choose to treat the first out
parameter as a return value or as the first out parameter.

 The note should probably go somewhere else than in the bullet, 
but I don't know where, really.
