Export UML2.1 - XMI 2.1 : irregularities

[mia]

Hi,
Using EA 7.0, I've exported my model in UML2.1 - XMI 2.1 and I've found 2 irregularities regarding the MOF UML2.1 specifications.
Some instances of "FinalNode" are exported while it is an abstract type.
Some instances of "ObjectNode" are exported while it is an abstract type.
Seems to be a bug, doen't it ?
Thanks,

Check the UML XMI specification.

Does the UML XMI specification authorize to create instances of abstract types ?!!
I don't think so !
FinalNode is abstract and has two concrete subtypes ActivityFinalNode and FlowFinalNode.
Instances of FinalNode should not be found in an exported xmi file...
Neither intances of ObjectNode...

Well, I took the time to look.

This was definitely allowed in XMI 1.x. I can find no prohibition in 2.x, particularly in the UML variant.

Here is the answer of your support :
"Regarding exporting the Activity Final Node:
EA currently exports this node a "uml:FinalNode" instead of "uml:ActivityFinalNode". This is a bug and we will have this issue fixed in the next release of EA.
  
Regarding "ObjectNode" :
EA should not allow creating an "ObjectNode" directly as it is an abstract class. We will have this issue fixed in the future releases of EA.
Hope this clarifies your issue. If you have any further queries, feel free to write-in.
