       <h2> Form internals </h2>
       <p> Form elements used for homework editing/response </p>
       <p> the form is named lonhomework </p>
       <h3> Viewing a problem (either CSTR or RES space)</h3>
       <ul>
         <li>
    grade_target, grade_username, grade_domain, grade_symb - the
    vaules take precedence over the the normal ENV settings of
    these, use &Apache::lonxml::whichuser() to get back the
    correct vaues of the items
         </li>
         <li>
    HWVAL_response:number - the name of the input elements for each response. The response is the response's ID, and the :number part exists only for response with multiple foils, and is a unique number in order of the submission
         </li>
         <li>
    changerandseed - the 'Change' button, only exists right after
    the Change button is clicked
         </li>
         <li>
    problemmode - in CSTR, it is either 'View','Edit','EditXML' or
    'Analyze' depending on the desired view
         </li>
         <li>
    rndseed - the currently requested random seed
         </li>
         <li>
    showallfoils - if it exists, and we are in CSTR space, the
    problem should ignore &lt;conceptgroup&gt; and the response's
    max setting and show all possible foils
         </li>
         <li>
    submit - the name of the Submit button
         </li>
         <li>
    submitted - a hidden form parameter that can be used to tell
    if the student has submitted answers or not, if it is set,
    there should be answers to grade.
         </li>
       </ul>
       <h3> Editing a problem (Edit mode)</h3>
       <p> tagdepth referes to the current value of the xmlparsers tagdepth couter ($Apache::lonxml::currentdepth)</p>
   <p> Note: the file edit.pm has many helper functions for creating the standard elements for editing a tag and it's attributes, all of those functions follow these conventions </p>
       <ul>
         <li>
    tagdepth_argname - I.E. 1_3.max, a parameter editing value,
    max is the name of the parameter and it is for the third tag
    inside the first tag
         </li>
         <li>
    delete_tagdepth - if set to yes, delete tag tagdepth and all
    tags inside of it
         </li>
         <li>
    homework_edit_tagdepth - used by both &Apache::edit::editline
    and &Apache::edit::editfield for the &lt;textarea&gt; and
    &lt;input&gt; form elements they create
         </li>
         <li>
    insert_tagdepth - used to request an tag insert, it is set to
    the id number of the requested tag in the
    %Apache::lonxml::insertlist
       </ul>
