[DFDL-WG] short form on xs:schema?

Mon Dec 5 07:57:15 CST 2011

Sorry Suman I don't understand what you are saying.  The following are 
identical. 

<xs:schema dfdl:ref="block" dfdl:encoding="ASCII" ...>
</xs:schema>

<xs:schema  ...>
        <xs:annotation>
                <xs:appinfo="www.ogf.or/dfdl/1.0">
                        <dfdl:format ref="block" dfdl:encoding="ASCII" />
                </xs:appinfo>
        </xs:annotation>
</xs:schema>

On another note, I am also looking at the real usefulness of providing 
this annotation in the short form on xs:schema as most of the time users 
would need a default format at the schema level referring either to 
DFDLFormat  ( General purpose DFDL format definition) and/or containing 
defaults for other attributes. 

We may want to provide for completeness but the same argument would hold 
for other dfdl attributes..

Suman 

That is exactly what Mike is suggesting. If you look at Table 7 in the 
spec (section 7.1) and the wording about short form in section 7.1.3.3 
then the natural assumption is that DFDL attributes on xs:schema would be 
allowed as the short form of the anonymous dfdl:format annotation's 
properties.  If a property occurs in both short form and attribute/element 
form that is a schema definition error as per section 7.1.3. 

So, are there any reasons why this should not be allowed?  I can recall 
this being discussed in the past but I don't remember a conclusion. The 
only reason I can think of is that it would easy for a human reader to 
miss DFDL properties on xs:schema because of all the namespace attributes 
that typically occur there.  But that's just a formatting/style thing.

One way to view this annotation would be as if it is defined on the 
default format at the xs:schema..   Question would be what if dfdl:format 
at xs:schema also has dfdl:encoding specified - which one would win ?..

I don't know that we ever talked about this.

Most schema constructs support short form

<xs:element ... dfdl:encoding="utf-8" />

Does the xs:schema itself support short form for the "default" format 
properties?

<xs:schema xmlns:xs="...."
  dfdl:encoding="utf-8">
...
</xs:schema>
