<conventiondeclaration> Convention Declaration

<conventiondeclaration> is a new element in EAD3 and an optional child element of <control>. It wraps <citation> elements used to identify rules or conventions (such as DACS) used to compile the description along with an abbreviation or description for them. The required <citation> may be paired with an <abbr> element to specify an abbreviation (DACS for Describing Archives: A Content Standard) and a <descriptivenote> to specify how the rules/conventions were used. It should be used separately for each convention cited.

If conventions used are defined locally, use <localtypedeclaration> instead.
