The IBM #486 exam is on the proper track. The Craig Larman book "Applying UML and Patterns" is the best intro book ever made in my opinion. Also "UML Distilled" by Martin Fowler is excellent material. More then just an exam I think the 486 is a great learning experience. I think the OMG exams are also good. I appreciate finding out about them on the Javaranch. I have not done the OMG exams but I see that they would be great to study for.
It is true that you do not get a certification for it. It needs to be used in combination with others to get Enterprise Developer. I think it really warrants its own certification.
The 486 starts to prepare you for going forward into other areas such as architecture. Books like "Software Architecture in Practice 2nd Edition" by Len Bass, Paul Clements and Rick Kazman and "Software Architecture" by David Dikel. Architecture in this area is not tested for anywhere. In a lot of ways this area goes beyond what UML can map. It goes into how to understand all of the influences that go against an architecture. And how those influences shape the system.
