Thanks for the clarification. 
 
I like the idea of adding "checkAvailability" to the address URL. The
change is checked in

	My earlier comment that it should be {checkAvailability} was
wrong.  It should remain as {checkInDate}.  

	 

	I believe that only leaf nodes can be specified.  Section 4.2
IRI style says it has to be a sequence.

	 

	As I read the spec, the example with location="{checkInDate}"
should become a URI option a).  Perhaps the example address attribute
should be updated to add the "checkAvailability" to be a more
descriptive URI.

	 

	Cheers,

	Dave

	Hi David,

	 

	While incorporating your suggestions below, I came across a few
more questions. Please see below.

		Subject: Primer Review

		I reviewed the primer for the HTTP binding and
ext/versioning examples.  I did find a few things that need or could use
changing.

		 

		2.5.6

		As DavidB suggests, the example should be
{checkAvailability}
		[Kevin] I don't quite understand your point here. Do you
mean change the value of whttp:location in example 2-12 to
"{CheckAvailability}"? That doesn't answer the question in the Ed note.

		 

		Let's have a closer look at the definition of
{CheckAvailability}

		 

		      <xs:element name="checkAvailability"
type="tCheckAvailability"/>    
		      <xs:complexType name="tCheckAvailability">     
		        <xs:sequence>      
		          <xs:element  name="checkInDate"
type="xs:date"/>      
		          <xs:element  name="checkOutDate"
type="xs:date"/>      
		          <xs:element  name="roomType"
type="xs:string"/>      
		        </xs:sequence>     
		      </xs:complexType>   

		 

		The question is what kind of elements can be assigned to
the whttp:location.  Should it only be "leaf" element such as
"checkInDate"? or can it be an element that is defined using a complex
type, such as CheckAvailability which contains three children elements.
In the following example, if we let whttp:location =
"{CheckAvailability}, then how the serialization works?   

		 

		If we let whttp:location= "{checkInDate}", should
"checkAvailability" be part of the URI? more specifically, should the
URI be a, b, or something else? 

		a.
http://greath.example.com/2004/5-5-5?checkOutDate=6-6-5&roomType=foo 

		b.
http://greath.example.com/2004/checkAvailability/5-5-5?checkOutDate=6-6-
5&roomType=foo
<http://greath.example.com/2004/checkAvailability/5-5-5?checkOutDate=6-6
-5&roomType=foo> . 

		 

		 

		 

		Upon further reflection, I'd suggest changing the
section a bit by having the first example use the safe attribute 

		 and then an example that shows methodDefault, rather
than the inverse as is done now.

		 

		I suggest that example 2-14 just shows setting the
defaultMethod.

		[Kevin]  you mean take whttp:methodDefault="GET" out
from example 2-12, and move it to example 2-14? 

		 

		
		 

		 5.2.5.1. Change "The reservation service can accept" to
"The reservation service is changed to a newer version that can accept"

		 

		5.2.5.3 s/Mandadtory/Mandatory/g

		 

		5.2.5.5 Formatting of example needs indenting, operation
needs closing >

		 

		5.2.5.7 Formatting of example needs indenting for
wsoap:action

		 

		5.2.5.8.  The example should be

		 

		<xs:element name="ghns2:makeReservation"
type="ghns:tmakeReservation"/>

		 

		<interface . . .>

		   <operation name="makeReservation">

		       <input messageLabel="In"
element="ghns2:makeReservation" />

		</interface>
