Design Table; Columns/Description get with SP???

Hi,

I'm using stored procedures to create an online data dictionary for
all of our dbs and I thought it would be very cool if there was a way
that I could somehow pull the columns description entered in the table
design view (lower pane) of EM. I have poked around, but have not
found a way. It is my suspcion that this may be impossible. Does any
smart person out there know?

Also want to pull pks and fks and other constraints, which I think I
can figure out how to do, but if anyone has any pointers, that would
also be appreciated.

Many Thanks,

Georgia
