Re: [dita] Radu's question and analysis of subjectScheme content in the DITA 1.3 spec

I'm pretty sure I agree with this analysis.

Cheers,

Subject:  [dita] Radu's question and analysis of subjectScheme content in the DITA 1.3 spec

    

  

    
I've read through both the Language Reference and ArchSpec topics
      carefully (and found a few glitches, which I've sent to the list).

    
I think we clearly and consistently make the following points:

    
      
For bound enumerations, the category value is NOT included in
        the list of permitted values; it just serves as the reference to
        the children values. We repeatedly explicitly state this in
        examples.

      

      
Key references to controlled values are resolved to key
        definitions "using the same precedence rules as apply to any
        other key."
http://docs.oasis-open.org/dita/dita/v1.3/os/part1-base/archSpec/base/subjectSchema.html#subjectSchema

      

    
    
Given Radu's example:

    
!DOCTYPE
        subjectScheme PUBLIC "-//OASIS//DTD DITA Subject Scheme Map//EN"
        "subjectScheme.dtd">
        

        <subjectScheme>
        

            <subjectdef keys="floatLeft">
        

                <subjectdef keys="left"/>
        

            </subjectdef>
        

            <subjectdef keys="outputclassFig">
        

                <subjectdef keys="none"/>
        

                <subjectdef keyref="floatLeft"/>
        

            </subjectdef>
        

            <enumerationdef>
        

                <attributedef name="outputclass"/>
        

                <subjectdef keyref="outputclassFig"/>
        

            </enumerationdef>
        

        </subjectScheme> 

      

    
I think processors need to resolve the key reference to
      "floatLeft" in place and so interpret the bound set of controlled
      values as follows:

    
    <subjectdef
        keys="outputclassFig"> 

                <subjectdef keys="none"/> 

                <subjectdef keys="floatLeft"> 

                  <subjectdef keys="left"/> 

                </subjectdef>

            </subjectdef> 

      

    
Note that the category value "outputclassFig" is not a permitted
      values for @outputclass.

    
Should we add this as an example to the DITA 1.3 errata?
