DITA 2.0 stage one proposal: Remove deprecated and "Reserved for future use" items

Folks, we've taken for granted that we'll remove
      deprecated/reserved for future use items (elements, attributes,
      domains, document types) in DITA 2.0.

    
However, I think we need a formal proposal for this, since it
      involves the following:

    
      
Topics for the spec about migration paths

      
Changes to grammar files

      
Usability considerations -- Is there anything that we DON'T
        want to remove? In particular, I wonder about @navtitle, since
        that might effect almost every DITA map in existence.

    
    
I started to compile a list of these items, which I'll paste
      below. (Things that it does not contain are the deprecated L &
      T domain and glossary grammar files.)

      Deprecated items
      
The following items have previously been listed in
        the DITA specification as deprecated. 

      

      
        

            Item
            Replacement
          

        
          

            <boolean>
            <state>
          

          

            @print
            @deliveryTarget
          

          

            @navtitle
            <navtitle>
          

          

            @longdescref
            <longdescref>
          

          

            @query
            No – Declared but never defined
          

          

            @role="sample"
              or @role="external"
            No – Deprecated since DITA 1.0; reason was
              compatibility with DeveloperWorks DITA.
          

          

            @type="internal"
              on <lq>
            @scope
              and @format
              on <lq>
          

          

            @type="external"
              on <lq>
            @scope
              and @format
              on <lq>
          

          

            @id
              on <resourceid>
            @appid
              on <resourceid>.
              Not a case of things being removed where documents might
              be broken.

The following items have previously been listed in the
      DITA specification as "Reserved for future use" or

            or <linklist>
          No – Typos in DTDs.
