Some very early work on a DTD for court opinions. This DTD was developed in 1999-2000 to markup the opinions issued by the US Circuit Court of Appeals. Work was done with an eye toward generalized use to mark up any court opinions. Though some testing was carried out with opinions from the 11th circuit, AFAIK the DTD was never implemented by any court. I am providing it now for the curious and because I still hear from people who are interested in marking up court opinions.
CourtOpinion.dtd is the original DTD that was developed for marking up court opinions. It was put together using a package called Near & Far Designer. For many years only this DTD existed.
CourtOpinion.rng is an intermediary RELAX NG file that I generated from the DTD using dtdinst so that I could generate the W3C XML Schema file.
CourtOpinion.xsd is an W3C XML Schema file that I generated from the RELAX NG file using Trang.
