Xerlin is an open source XML editor for the Java 2 platform[1] released under an Apache style license.
ChannelPoint founded and hosted the Merlot XML Editor as an open source project during 2000-2001.
Xerlin was created to build on those foundations and in fact used some of the same developers.
[3] Xerlin runs on any Java 2 virtual machine (JDK1.2.2 or higher).
The application is extensible via custom editor interfaces that can be added for individual DTD's.
