According to MOF constraints, everything but a package needs to have a 
container. So only packages do not need to have containers. Given that, 
it is clear, that transitively everything in MOF needs to be contained 
in a package or needs to be the package itself. So that's why you need 
to create your models in such a way that all the classes are contained 
in a MOF package. Now according to MOF profile 
(http://mdr.netbeans.org/uml2mof/profile.html), MOF package can be 
represented in UML using either UML Model or UML Package with 
<<metamodel>> stereotype.
If you realize the above, it should be clear to you why it works the way 
you describe.
BTW, why do you need UML2MOF tool? From your second question it seems to 
me that you do not need to convert UML models to MOF. You can generate 
the code from the UML models directly (by accessing them in a similar 
way as the UML2MOF tool).

Absolutely. You can use MDR to parse the XMI exported from the UML tool, 
then traverse through the model using JMI API generated from UML 
metamodel and generate the code.
