Class UML 2.5::ExtensionEnd
Description:
An extension end is used to tie an extension to a stereotype when extending
a metaclass. The default multiplicity of an extension end is 0..1.

ExtensionEndThis redefinition changes the default multiplicity of association ends,
since model elements are usually extended by 0 or 1 instance of the extension
stereotype.

NamedElementA name that allows the NamedElement to be identified within a hierarchy
of nested Namespaces. It is constructed from the names of the containing
Namespaces starting at the root of the hierarchy and ending with the name
of the NamedElement itself.

Operations:
Signature: lowerBound() : Integer;
Description: The query lowerBound() returns the lower bound of the multiplicity as an
Integer. This is a redefinition of the default lower bound, which normally,
for MultiplicityElements, evaluates to 1 if empty.
Expression: result = (if lowerValue=null then 0 else lowerValue.integerValue() endif)
