Re: [dita-lightweight-dita] LW DITA DTDs updated

Hi Birgit,

    

    The reason we avoid W3C XML Schema, especially for standards
    purposes, is that because the XML Schema redefine feature (which we
    use) is defined in an ambiguous way. See this by Eliot Kimber:

    

http://www.xiruss.org/tutorials/dita-specialization/body/part-config-and-extend/dtd-or-xsd.html

    

    And actually, the official schema for DITA is RelaxNG as of a year
    or so ago, but I think we are using DTDs in the beginning here for
    preliminary work on LW DITA because most of us are familiar with it
    and it's easy.

Dear Mark and others,

        
Thanks for updating the DTDs.

        
Anyway, I wonder why we (LW DITA)/you still
            using DTDs instead of XML Schema. My experience is that XML
            Schema is much more easy to use for specializations and
            furthermore there are tools which cannot read DTDs anymore
            but XML Schema well. 

        
Kind regards, Birgit

I updated the Lightweight DITA DTDs to cut
          things down to just topic and map. The files are in the form
          of an OT plugin here:

          

          https://tools.oasis-open.org/version-control/svn/dita/subcommittees/LightweightDITA/org.oasis.lwdita

          

          I created branch 0.1 to hold all of the old files, including
          concept, reference and task files:

          

          https://tools.oasis-open.org/version-control/svn/dita/subcommittees/LightweightDITA/branches/0.1

          

          Questions:

        
          
I left in the highlight domain but I'm not sure
            if I should have. Get rid of it?

          
I didn't change anything with map but I noticed
            that it requires a topicmeta under a topicref. Is this
            correct or are we removing this requirement also?

        
        
Thanks to Carlos Evia for assistance!
