Then again, teaching people the possible future benefits accrued by=20
standardization for future data collection (application schemas) makes good=

sense. (I think this is happening: I see some migration to XML-everything,=

including GML.)
Your proposal in any case is a concrete one, rather than RAND's 237-page=20
(non)conclusion that perhaps federal GI-related agencies should look at the=
=20
security issue. How many millions$ did it take to come up with that?
