Fixed. Also moved it to a better location: http://srw.cheshire3.org/extensions/requestedTerm.html Now, here's a question: If parameter names are case sensitive (which I believe that they are as XML is case sensitive), then X-foo and x-foo are different parameters. Should we be more explicit in the documenation at http://www.loc.gov/z3950/agency/zing/srw/extra-data.html that the x must be lower case? Rob -- ,'/:.
