[Moims-dai] Architecture Description

[Mark Conrad]

" I cannot understand why Content_Information (a sub-type of
Information_Object) shows methods get/putPreservationDescriptionInformation.
That would normally indicate that these are additional methods in addition
to those which Information_Object has – but why? "

Because PDI does not apply to all Information_Objects - only
Content_Information.
