Subject: Schema Structure - Response to request for structure




From: Chin Chee-Kai <>
To: UBL NDRSC <>
Date: Thu, 2 Oct 2003 18:50:16 +0800 (SGT)






Here it is.  This describes the way the 8 main document schemas
are structured.  The header portions (up till and including
"Imports") are applicable across all schemas in the "xsd"
directory,  including Reusable, CodeLists, CCT and 
CoreComponentParameters.  For the last 2 (CCT and 
CoreComponentParameters), the non-applicable portions are
addressed by the description "if applicable".

Hope this helps.

<!-- Comment:
     A UTF-8 encoding is adopted throughout UBL schemas.

<!-- ===== Version ===== -->
[
    version attribute first if used,                   followed by

<!-- ===== Namespaces ===== -->
[
    xmlns:xsd attribute if applicable,                 followed by
    targetNamespace attribute if applicable,           followed by
    xmlns default namespace attribute if applicable,   followed by
    non-codelist namespace declarations if applicable, followed by
    codelist namespace declarations,                   followed by

<!-- Comment:
    codelist namespaces are declared only if they are used
        in the schema, and are otherwise not declared.         -->


<!-- ===== Form Defaults ===== -->
[
    elementFormDefault attribute if applicable,        followed by
    attributeFormDefault attribute if applicable,      followed by

<!-- ===== Others ===== -->
[
    other schema attributes with schema namespace,     followed by
    other schema attributes with non-schema namespace

<!-- ===== Imports ===== -->
    CoreComponentParameters (metadata schema),         followed by
    CCT if applicable,                                 followed by
    RT if applicable, (NOT USED)                       followed by
    DT if applicable, (NOT USED)                       followed by
    BBIEs if applicable, (NOT USED)                    followed by
    ABIEs if applicable, (AS Reusable CAT),            followed by
    codelist schemas if applicable                     followed by

<!-- Comment:
    CoreComponentParameters is the most independent schema
       as it does not depend on other imports, and would need
       to be kept this way.
    CCT currently is independent of CoreComponentParameters
       but this may change if CCT has use of CoreComponentParameters.
    RT, DT, BBIE imports are not used in UBL.
    CAT is imported by all document schemas.
    codelist schemas are imported only if they are used
       within the document, and otherwise not imported.        -->





<!-- The following is applicable for Main Document schemas only -->


<!-- ===== Global Attributes ===== -->
(NOT USED)



Root Element
<!-- ===== Root Element ===== -->

<!-- ===== Root Element's Type Definition ===== -->

<!-- Comment:
     The root element's type definition is defined immediately
     following the definition of global root element to 
     provide clear visibility of the root element's type,
     of which this particular schema is all about.           -->



<!-- ===== Referenced Element Declarations ===== -->

<!-- Comment:
     These elements are defined only when they are referenced
     within the Root Element's Type Definition.
