  7. 6 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.
