   (http://home.earthlink.net/~salhir/#theobjectorientedparadigm)

*  Extending the Unified Modeling Language (UML)
   (http://home.earthlink.net/~salhir/#extendingtheuml)
   This paper elaborates on extending the UML and explores the
necessity, sufficiency, and consistency of the UML’s extension
mechanisms to conclude that there are inconsistencies with the UML’s
extension mechanisms..

*  "Unified Modeling Language Extension Mechanisms"
   [Distributed Computing magazine, December 1998]

   This paper also very briefly introduces the Core Modeling Language
(CML).
