Regular expression checking is done with Apache Foundation Regexp.
DTD source highlighting is done with JHighlight.
Gert Baudoncq provided info helping to track down some bugs.
Eduardo Bergasa Balda made some very annoying requests like i18n stuff :) :) :). He also provided the spanish sample.
Jens Bachmann brought in useful patches for <PRE> tag support and '%' char escaping.
Michael Koehrsen made a huge contribution by first integrating the element tree browser (thanks Mike !). Mike's work is based on Javascript code from Geir Landrö.

A few other anonymous people who provided some insightful comments and bug reports.
James Strachan provided help for "Maven-ification" of DTDDoc (~~still have to wait though~~ the wait is over James !).
