DynaText is an SGML publishing tool. It was introduced in 1990, and was the first system to handle arbitrarily large SGML documents, and to render them according to multiple style-sheets that could be switched at will. DynaText and its Web sibling DynaWeb won multiple Seybold and other awards, and there are eleven US Patents related to the DynaText technology: 5,557,722; 5,644,776; 5,708,806; 5,893,109; 5,983,248; 6,055,544; 6,101,511; 6,101,512; 6,105,044; 6,167,409; and 6,546,406.
