yes, I was reading this for a while, figured I would respond.

ok, this makes sense.

I just tend to think on this level.
specifying on this level, however, may become necessary in the formation of 
an actual format.

it does give me ideas though, maybe I could try for a general "store" format 
for my own use, which could be useful for my efforts...
said store format, however, will not be viewed as portable, but may try to 
represent general xml-style data (or be serializable to textual xml...).
