For any of the 6 basic components (group, attributeGroup, element,
attribute, simpleType, complexType), you need to differentiate global
definitions from local references (although they share the same element
name) and for element, attribute, simpleType, complexType you have a
third instanciation that's local definitions.

W3C XML Schema has adopted a rule of the thumb to split the attributes
in these instanciations of the same element types and this rule is that
global definitions never carry any information about the number of
occurrences and that this is a property of local definitions or
references.
