     Apache Todos DTD (Version 1.0)

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 document PUBLIC
       "-//APACHE//DTD Todo Vx.yz//EN"
       "todo-vxyz.dtd">

  where 
  
    x := major version
    y := minor version
    z := status identifier (optional)
      
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.
