+
+     Apache Todos DTD (Version 1.2)
+
+PURPOSE:
+  This DTD was developed to create a simple yet powerful document
+  type for software development todo lists for use with the Apache projects.
+  It is an XML-compliant DTD and it's maintained by the Apache XML
+  project.
+
+TYPICAL INVOCATION:
+
+  <!DOCTYPE todo PUBLIC
+       "-//APACHE//DTD Todo Vx.y//EN"
+       "todo-vxy.dtd">
+
+  where
+
+    x := major version
+    y := minor version
+
+NOTES:
+  It is important, expecially in open developped software projects, to keep
+  track of software changes that need to be done, planned features, development
+  assignment, etc. in order to allow better work parallelization and create
+  an entry point for people that want to help. This DTD wants to provide
+  a solid foundation to provide such information and to allow it to be
+  published as well as distributed in a common format.
+
+FIXME:
+  - do we need anymore working contexts? (SM)
