I think these attributes are used for difference purposes. We use the 'type' attribute to trigger the stylesheet to display a particular label and we don't generally normalize except in the high-level <did> or at the component collection level <c01>. So one functions as a qualifier to the type of data and the other encodes the data to machine-readable standards.

Any date range would necessarily be inclusive (including a bulk date range), right? The only time that the range would need to be differentiated would be if it was a bulk range. > > I'm reminded of the "Two dozen and one greyhounds" Simpsons episode, when Lisa asks, "Mom, why do I have to wear a flea collar?"

On the other hand, I agree that using inclusive for something like 2010-07-29 is a bit redundant :) > > Michele
