The figure on the Background pages includes a number of things I'm curious about:

• Is there a difference between the solid arrows (from the left hand side icons to the MDI System), the dashed arrows (from the MDI system) and the double-headed blue arrow (from MDI system to the state registry)? If so, please clarify the distinctions?
• The Current Project description does talk about MDI to EDRS flow of data. Is this represented in the diagram? Is the State Death Certificate Registry the EDRS? If so, that would be good to include in the icon label. If not, where does the EDRS fit in the figure?
