Concept Requirements

For each concept a requirement is given that determines whether this concept is desirable. The syntax is given in conceptrelations.dtd.
Example:

<concept>
  <conceptname>
    author
  </conceptname>
  <relationexpression>
    ahs>70 and user > 70
  </relationexpression>
</concept>

A small authoring tool, called "ReqTool", can be used to edit this xml file. It uses a "ReqApplet", and is activated to a special login button on the registration form. The tool is self explanatory.
