Overview
This document shows the relationship of Storage Units in a Draft.
Draft and Persistent Storage
The first diagram shows an example document with a TextPart Embedded in a DrawPart.
The second diagram shows the relationship of the Storage Units of the example document when the document is saved to Persistent Storage. Note that this diagram is simplified in a couple of ways:
1) Storage Unit Values are not shown.
2) The Property kODPropContents is assumed not to have other references other than those
to the Frames. This is usually not the case.
3) It is a standard that Display Frames are stored in a Property. Please see the Display Frame 'ternalization recipe in Part Persistency for more info. They are stored in the Part's Storage Unit, and should only be weakly referenced.
