Re: [mdr-users] question about mof metadata layer

Hi Ludger,
you are right regarding the notation. Although, MOF 1.4 has no formally 
defined notation, the UML notation can be used easily for it.
Regarding the contained element, yes, this is in fact a constraint on 
what kinds of elements a given construct can contain. It is not defined 
formally in the XMI. You can implement it manually in Java in case of MDR.
