In SDD1.1RC2 the uniqueness constraint(<nop>CharacterStateKey) on <nop>StateDefinition's ensure's that global states cannot be referenced more than once within Characters in a Terminology. This is because of
|
|
<verbatim>
|
|
<xs:field xpath="@id|@ref"/>
|
|
</verbatim>
|
|
in the identity constraint declaration.
|
|
|
|
This issue is illustrated with the example below. Attempting to reference 'efg301' more than once results in a validation error.
|
|
<verbatim>
|
|
...
|
|
<ConceptStates>
|
|
<StateDefinition id="efg301">
|
|
<Representation>
|
|
<Label xml:lang="en" audience="efg2">brown</Label>
|
|
</Representation>
|
|
</StateDefinition>
|
|
....
|
|
<CategoricalCharacter id="efg458">
|
|
<Representation>
|
|
<Label xml:lang="en" audience="efg2">Flower Color</Label>
|
|
</Representation>
|
|
<States>
|
|
<StateReference ref="efg301"/>
|
|
</States>
|
|
</CategoricalCharacter>
|
|
<CategoricalCharacter id="efg459">
|
|
<Representation>
|
|
<Label xml:lang="en" audience="efg2">Leaf Color</Label>
|
|
</Representation>
|
|
<States>
|
|
<StateReference ref="efg301"/>
|
|
</States>
|
|
</CategoricalCharacter>
|
|
</verbatim>
|
|
|
|
A solution will be to declare both !ConceptStateKey and !CharacterStateKey as follows
|
|
<verbatim>
|
|
<xs:unique name="SomeUniqueName">
|
|
|
|
<xs:selector xpath=".//u:StateDefinition"/>
|
|
<xs:field xpath="@id"/>
|
|
</xs:unique>
|
|
</verbatim>
|
|
|
|
This ensures that id's on <nop>StateDefinition's are unique throughout a document.
|
|
|
|
I have implemented this in BDI.SDD_.xsd at rev 39 of the Subversion trunk

The issue seems indeed to be a bug. I believe that the result should make sure that:
|
|
* concept state id-values are unique within the entire document (not only within a single concept).
|
|
* concept state references are unique within the scope of a single character. If the latter is truly difficult, we could drop the constraint.
|
|
|
|
Did we have any other intentions? I cannot remember.
|
|
|
|
At the moment I cannot follow your proposed solution - please check for me whether the constraint above are stated correctly, and whether your solution fullfills them.

Thanks!
