    Title: RE: [emergency] EDXL DE - XML Schema Issue
    After our meeting Monday, I thought of why we didn't have incidentID in the DE - because it may contain payloads related to different incidents. That's why we moved incidentID to the keyword field.
     
    The question in my mind is - is it good enough to be an initial standard? We can certainly iron out minor issues in EDXL-DE 1.1, as long as there are no show-stopping issues unaddressed.
     
    I have voted yes to both, but I could be persuaded to change them, if I become convinced that there are any show-stopping issues.

    I am concerned that what we have put together is not yet ready, and that
    we are taxing those that have volunteered to put the final touches on
    our work too heavily.  Do we want to create a situation, like we did
    with CAP 1.0, where something important gets dropped?  Personally, I
    would rather wait one more month than get it wrong in some minor, but
    potentially embarrassing, way.  Right now, I intend to vote for the
    committee draft, but not for the release for vote.  My mind could be
    changed if, in fact, a final product is ready and usable as an example
    before the voting deadline.  I am afraid, however, that we do not have
    time to do the quality control review needed to get it all right before
    we put or product out for public inspection.

    There are a few major/minor issues with the XML Schema used in EDXL DE
    CD 1.0 (19 Aug 2005).

    Major:
    1 - It does not support ANY reusability as all the elements and
    datatypes are locally defined.
           (Common datatypes should be globally defined and reused, for
    example for valueListURN.)

    2 - It uses full element names (including the angle brackets) in the
    Annotation elements which
           renders it as an *invalid* schema (tested with XML Spy and
    Oxygen).

    3 - It does not define attributes that are mandatory (eg for circle and
    polygon).

    4 - Does not support a single top level parent element which means that
    having a valid EDXLdistribution
           is not possible.

    5 - valueListURN and value elements can occur in semantically incorrect
    sequences.

    Minor:
    1 - It references Schemas to import that are not required.

    2 - It is extremely verbose as it repeats all the documentation from
           the specification in the annotation elements (double maintenance
    effort required)
           and difficult to read.

    3 - Should define the targetNamespace as the default namespace.


    I am happy to propose an updated XML Schema that addresses the above is
    the TC feels this is appropriate.
