My reading of the specs tells me that there are three common "parts" handled by DrawingML.
Those are Charts, Diagrams, and Themes. The only real difference between the three project
areas (Spreadsheet, document, presentation) vs. DrawingML is the way the part in question
is referenced in the package. This could be handled in the createChart, createDiagram, or
createTheme methods the specific package.

For the binary formats, we have the "DDF" package which contains the common drawing records
and classes. Sounds like we might be able to create a XDDF package for the common DrawingML
drawing xml stuff too!
