RE: Its time to publish 2nd draft

Valentina,

 

Thanks  for taking care of these points.

 

Regarding the point for which you could not find the reference: in
section 4.1.1.2:

 

If a reference element is recognized as null, then processors MUST NOT
attempt to resolve it.

 

And in 4.1.2.3: A model validator
<http://dev.w3.org/cvsweb/~checkout~/2007/xml/sml/build/sml.html?content
-type=text/html;%20charset=utf-8#model_validator>  MUST not attempt to
resolve null references.

 

But section 4.1.2.4 (defining deref() ) says:

 

*	The output node set contains no element node corresponding to R
if any of the following conditions is true

	*	. . .
	*	R is a null reference

Which seems to define an output (the same output for not finding a
reference in a model) for dereferencing a null reference.

<vp>All types in this sample are called  somethingType, for that reason
I guess we should keep the 'Type' suffix for the reference types as
well</vp> 

The rest are non-editorial issues

Here are some comments-that I was able to complete on the plane.
(Again, regrets regarding this week's meeting; I will not be able to
make it. 
  
The Abstract still mentions XML Schema "profile."  (Also don't we have
to also clean up using "profile" with regard to Schematron?) 
  
In the Introduction: a period is needed at the end of the bold sentence
in item #2. 
  
IMHO, the definition of Rules in section 5 should restrict XML Schema to
just version 1.0, since 1.1 now contains a simple constraint language. 
  
I would recommend that the new example of using sml:nilref="true" in
section 4.1 include the <Name> and <Grade> elements from the example
above to more clearly make the distinction between xsi:nil="true" and
sml:nilref="true"  Perhaps some verbiage following the example would be
helpful to further explain null references and contrast that with the
sml:ref="false". 
  
Two questions: 
1.        Something to think about for the future:  What does "resolves"
apply to: a scheme or a reference?  Well, both, which makes the use of
"reference" float between these two levels.  I would suggest that
reference elements refer while schemes point.  I think making this
distinction will alleviate any confusion that may arise from the current
text. 
2.        Given the discussion we had about validators vs. consumers
with regard dereferencing behaviors, why MUST a validator provide an
implementation for deref()?  A validator must apply "strict" validation
to references, which is different behavior from deref. 
  
Why do we say that a validator MUST not try to deref a null reference
when in fact we define an output (0 nodes) for a null reference? 
  
Section 4.2.1 states, "if a model validator chooses to represent
references with the URI scheme".  Since when does the validator "choose
to represent references"?  Isn't that the role of the document producer?

  
I would suggest changing all the names ending in "...RefType" in the
example in section 4.4.1 to simply "...Reference". 
  
  
In SML-IF, the following statement is made in section 2.2: 
      See section 6, "Equivalence," and section 5 "Reference Resolution"
in particular. 
      There currently are no sections 5 and 6 in the document.
