CR109: Two options

In fulfillment of my editorial item, I have come accross the following 
issue.

There are 2 ways implement the resolution for CR issue 109:
a. restrict the {soap fault code} property to the 5 allowed QNames, when 
the underlying protocol is SOAP 1.2; or

b. restrict instead the <wsoap:code> EII.

(c. = a.+b. seems an overkill)

Pros:
a. Easier to implement (spec-wise).

b. Disallows invalid XML in the first place.

Cons:
a. The XML may be valid whilst the component model isn't. (Does this 
matter?)

b. Difficult to represent in the pseudo-code and in the schema.

Which option does the WG want the editors to implement? I suggest a. for 
ease of implementation.
