The UBL TC has not yet come to a final decision on all the details of the extension methodology to be followed by those using and customizing the UBL core libraries. It is anticipated that there will be a need for users to customize the core library, however, and much work has been done in this area. The following points should be borne in mind during review of this UBL Library release, as being probable features of future releases:
Those interested in further understanding of the anticipated extension methodology should see the white papers found at the Naming and Design Rules Sub-committee section of the UBL portal (http://www.oasis-open.org/committees/ubl/ndrsc/).
The current release conforms with the existing NDR rule which states that all elements will be globally declared. The issue of global versus local element declarations, although decided by NDR, is being revisited at the request of a minority group within NDR. It is possible that the existing global declaration rule may be changed in the future. For those wishing to learn more about the issues surrounding this debate, please see the UBL TC section on the OASIS website.
In this release, the global elements have no documentation in their declarations: the use of these elements within each type declaration is documented. Global elements that appear in the UBL Library will be fully documented for future releases, both where they are used within types, and independently where they are declared.Last modified: January 27, 2003/11:46am CST
