Issues

  • Issues implementing UBL;

    • Application Extendability and Reusability

      • We like to have application framework which allows both extendability and reusability.

    • Difference in extension rule for UBL and JAXB

      • In JAXB, XML Schema “extension” is treated as “extend” of Java.

      • If UBL extension was implemented as XML Schema “extension”, we could reuse and extend business logic which handles original UBL.
