Sibling and Non-Sibling Occurrences

Sibling and Non-Sibling Occurrences

A key uniquely identifies sibling occurrences of an element. It is permitted for non-sibling occurrences to have the same key.
Consider the following XML structure:
<Report> <Company> <Employee ID="1">John</Employee> <Employee ID="2">Leslie</Employee> </Company> <Company> <Employee ID="1">Marie</Employee> <Employee ID="2">Larry</Employee> </Company> </Report>
attribute can be a valid key for
because it uniquely identifies an
within a single
. The duplication of
values in different
elements does not invalidate the key.
