Hi,

Are both of the heavyweight and the middleweight extensions that you
illustrated are considered the (first-class extensibility)heavyweight
extension mechanism that specified by the UML specification?

In many articles and papers, it refers to the heavyweight extension that
was defined by the MOF. I opened the MOF specification and I didn't
any mention to heavyweight or first-class extensibility. The only thing
that I found is Extension package, which I didn't understand its usage.
Do you clear this to me?

Are the package import and emerge considered essential steps while
applying the heavyweight extension?

Thanks in advance,

Manar
