I reviewed Part 2 carefully and have the following questions up to the end 
of chapter 5:

1. In 4.2 IRI Style, the content model of the initial is constrained to 
have a sequence of child elements. What are the occurrence contraints? Are 
there any?

2. In 4.2 IRI Style, the last bullet says: "If the children elements of 
the sequence are defined using an XML Schema type ...". What else could 
they be defined as? Don't all elements have a type?

3. In 5.3 SOAP Binding Rules, the rule about mustUnderstand seems weak. If 
the SOAP Header block is marked as mustUnderstand=true in WSDL, then 
shouldn't the header in the SOAP message also have mustUnderstand=true?

4. In 5.6.2, isn't {soap fault codes} really a set and not a list? The 
order of subcodes is irrelevant and it doesn't make sense to repeat a 
subcode. Sounds like a set. Also, is there a difference between having an 
empty set of subcodes and #any. I assume #any means any subcode may be 
used. Does an empty set mean the subcodes are never used?

5. Global comment on organization: Part 1 is organized by component, and 
then by properties within a component. In Part 2 this structure in not 
used. Components and properties are described together. I think it would 
be clearer is we followed the Part 1 organization, i.e. have a section for 
each Core and Extension component involved, then list and describe the 
properties that apply to each compoinent. e.g. 5.7.2 lists a set of 
properties, but some apply to Binding and some apply to Binding Operation 
- sort of confusing I think.

6. In 5.7.2 is there any constraint between WSDL meps and SOAP meps, i.e. 
if an operation uses a given WSDL mep, then does that restrict the allowed 
SOAP mep used in the biniding?

7. In 5.7.2 there are defaulting rules for {soap mep} but is a value for 
the actual SOAP mep required, i.e. must the defaulting rules produce a 
definite value?

8. In 5.8.2 there should be a constraint on {soap modules} that each soap 
module component is uniquely identified by its {ref} property, i.e {ref} 
is a key. No two different soap modules in the {soap modules} property may 
have the same {ref}.

9. Similarly, in 5.9.2 there should be a contraints on {soap headers} that 
each soap header component is uniquely identified by is {element 
declaration} property (I assume).

10. In 5.9.6, the design of the fragment identifier for wsoap.header is 
inconsistent since it represents the element QName as namespace#name. All 
other components use the QName and define the namespace using an xmlns 
pointer part. This should be changed to use QName too, c.f. the element 
declaration component itself.
