The following subclauses name and define the rules and cases to which topic map graph components and entire topic map graphs must conform in order to be considered "well formed", and the additional rules to which topic map graphs must conform in order to be considered "fully merged". Topic map graphs that are under construction may or may not be well-formed, but only well-formed topic map graphs are eligible to become fully merged, in addition to being well-formed.
