Namespaces are commonly structured as hierarchies to allow reuse of names in different contexts.  As an analogy, consider a system of naming of people where each person has a proper name, as well as a family name shared with their relatives.  If the first names of family members are unique only within each family, then each person can be uniquely identified by the combination of first name and family name; there is only one Jane Doe, though there may be many Janes.  Within the namespace of the Doe family, just “Jane” suffices to unambiguously designate this person, while within the “global” namespace of all people, the full name must be used.

Итак, в этом примере «Джейн» — это имя, а «Доу» — это пространство имен.
