it's really because of the reflective layer. the standard is built around an 
object model in which everything has a common base and its type can be 
"easily" determined. remember, the uml api was originally written in idl for 
corba. corba has a really complex type system that lets you do that. 
languages like java and c# have that style of type system built in.

it gets really complicated when you start dealing with collections. templates 
don't translate too well to this style of object model.

the solution i used with omf was to basically re-create this concept, although 
i tried to keep it as light as possible. i didn't do such a good job - 
although its not as complex as corba :)
