Hi John, I am beginning to have some regrets about what I did yesterday in terms of misusing <documentation> by adding a name field. I think it would make more sense to have a <document> tag that has both a name and a link: documentation should be special (a special document???) and separate. So I would have something like this: ... <documentation xlink:href="http://iridl.ldeo.columbia.edu/SOURCES/.LEVITUS94/.dataset_documentation.html" /> <document xlink:href="http://iridl.ldeo.columbia.edu/SOURCES/.LEVITUS94/.oceanviews.html" name="oceanviews"/> <document xlink:href="http://iridl.ldeo.columbia.edu/SOURCES/.LEVITUS94/.oceanviews2.html" name="oceanviews2"/> <document xlink:href="http://iridl.ldeo.columbia.edu/SOURCES/.LEVITUS94/.Zmix.html" name="Zmix"/> ... Does this make sense to you? Benno -- Dr. M.
