                        <xs:documentation>This field is a string which contains a list of assignments 
of the form &lt;br /&gt;
  &lt;tt&gt; key = value &lt;/tt&gt;&lt;br /&gt;
  where each &lt;tt&gt;key&lt;/tt&gt; is the name of a variable local to the question, and &lt;tt&gt;value&lt;/tt&gt;
  is an expression in Maxima&apos;s language.  When a question is instantiated, this list is
  passed to the CAS, and evaluated in order.  The value obtained for
  each &lt;tt&gt;key&lt;/tt&gt; will be stored and used later, for example in the
  question marking routines.  The keys need not be unique, although only the last
  value will be available for use later.

  &lt;p&gt;&lt;b&gt;Maxima&apos;s assignments &lt;tt&gt;a:3&lt;/tt&gt;&lt;/b&gt;&lt;br /&gt;
  Computer algebra systems each use a different syntax to denote the assignment of a value to
  a variable.  For example, Maple and Derive use &lt;tt&gt;:=&lt;/tt&gt;. Mathematica uses 
  &lt;tt&gt;=&lt;/tt&gt; or &lt;tt&gt;:=&lt;/tt&gt;, depending on when the assignment is to take place.  Maxima uses
  the form &lt;tt&gt;key:value&lt;/tt&gt;, which is unusual and not intuitive.   
  Maxima reserves &lt;tt&gt;:=&lt;/tt&gt; to denote &lt;em&gt;function&lt;/em&gt; definition, eg &lt;tt&gt;f(x):=x^2&lt;/tt&gt;.
  Hence, in STACK we add an abstraction layer to enforce a syntax where 
  every expression must be of the form &lt;tt&gt; key = value &lt;/tt&gt;.&lt;/p&gt; 

  &lt;p&gt;Examples are included in the authoring guide.&lt;/p&gt;

  &lt;p&gt;&lt;b&gt;Notes&lt;/b&gt;
  &lt;ul&gt;
  &lt;li&gt;Items are separated by either a newline or ;&lt;/li&gt;
  &lt;li&gt;If you type a string not in the form &lt;tt&gt; key = value&lt;/tt&gt;, a variable name such as &lt;tt&gt;dumvar3&lt;/tt&gt;
  will be assigned automatically to keep track of the command in the list of question variables.&lt;/li&gt;
  &lt;li&gt;These raw values are internalized as a PHP array, in this case stored in &lt;tt&gt;questionVars&lt;/tt&gt;.
  Hence, the field may change when you edit the question.&lt;/li&gt;
  &lt;li&gt;If a student uses a variable which has been assigned a value, the value will be used instead during
  the marking procedure.  Hence, if you ask the student for an expression such as 
  &lt;tt&gt;x^2-n&lt;/tt&gt; in a question, it would be better not to use &lt;tt&gt;n&lt;/tt&gt; here in case
  a student literally types this expression.

There are a variety of such tools, and others could easily be substituted, although it

javascript in the page, and so on.

                        <xs:documentation>A syntax hint allows the teacher to
give the student a pro-forma in the input box.  This can include &apos;?&apos; characters
(which the CAS treats as the special variable &lt;tt&gt;qmchar&lt;/tt&gt;).  
The syntax hint will appear in the answer box, whenever this is left blank by the student.
For example, rather than having to type
&lt;pre&gt;matrix([1,2],[3,4])&lt;/pre&gt;
the teacher may want to provide an answer box which already contains the string
&lt;pre&gt;matrix([?,?],[?,?])&lt;/pre&gt;
instead.  The student then need only to edit this, to replace ?&apos;s with their values.
This helps reduce syntax error problems with more difficult syntax issues.
The ? may also be used to give partial credit.
Of course it could also be used for general expressions such as
&lt;pre&gt;x^2+?*x+1&lt;/pre&gt;

The mark modification method is a function which applies to the list of raw marks, and returns a mark for this attempt.  
There are two mark modification methods.
&lt;ul&gt;
&lt;li&gt;&lt;b&gt;Penalty&lt;/b&gt;&lt;br /&gt;
This is the default method, which has been tried for many years using the AiM system.
For each incorrect attempt, which is valid and the student asks to be marked, a penalty is accumulated.  
The AttemptMark is the AccumulatedPenalty for that attempt, subtracted from the RawMark.  
The mark for this attempt is the maximum AttemptMark.  Thus a mark cannot &apos;go down&apos;.  This prevents a student for being penalized for
continuing to try to gain credit. 
&lt;/li&gt;
&lt;li&gt;&lt;b&gt;Last Answer&lt;/b&gt;&lt;br /&gt;
This is the RawMark for this attempt, and disregards all penalties and previous answers.  Note, this is different
from setting the penalty to be zero, and using the penalty scheme above.  With this method if a student leaves
an incorrect answer in place they will not be given credit for any previous correct attempt.
&lt;/li&gt;

                                    <xs:documentation>This literally asks &quot;Apply which later test?&quot;.  It must be the number of an
   existing potential response. This will allow branching and the construction of tree like flow charts
   for the execution of feedback or partial credit.  There are two provisos:   &lt;ul&gt;&lt;li&gt; No potential response is executed
   more than once.  If this happens, the marking scheme bails out and takes no further action.  This
   is to prevent loops.&lt;/li&gt; &lt;li&gt; If the value of this field does not correspond to a legitimate
   Potential response, then the marking scheme bails out and takes no further action.&lt;/li&gt;&lt;/ul&gt;  This latter
   can be used to advantage by assigning the field a value of -1 to indicate the end of the process.
   &lt;p&gt; The default blank potential responses do not jump, but finish the process.</xs:documentation>

    stackQuestion as expected.
  - AnsTest values to be written out in schema.
! 
! Issues when running STACK with IIS instead of Apache:
! - Must give read+execute access to the cmd.exe file from the IUSR_Guest account in order to open processes. Not the best solution - is a
!   potentially serious security hole
! - Must give full permissions to the stack-1-0 directory by using the IIS snap-in in Computer Management - also must add 'index.php' to list
!   of default web pages
! - various mYSQL issues: cannot use the latest version of mySQL with PHP4 over iis due to the use of more secure authentication: 
! - tmp directory within stack-1-0 - to make writable, the IUSR_Guest account must have full control of it.

! - In the potential response schema structure, the possible enumerations for RawMarkMod and AnsTest are not output. This
!   is a known issue and is due to the $markmods array which holds the possible values being present in stackAuthor - not

! - AnsTest values to be written out in schema.

      DCMES 1.1 XML Schema
      XML Schema for http://purl.org/dc/elements/1.1/ namespace

      Created 2003-04-02

      Created by 

      Tim Cole (t-...@ui...)

      Pete Johnston (p.j...@uk...),
      Carl Lagoze (la...@cs...)

      This schema declares XML elements for the 15 DC elements from the
      http://purl.org/dc/elements/1.1/ namespace.

      It defines a complexType SimpleLiteral which permits mixed content 
      and makes the xml:lang attribute available. It disallows child elements by
      use of minOcccurs/maxOccurs.

      However, this complexType does permit the derivation of other complexTypes
      which would permit child elements.

      All elements are declared as substitutable for the abstract element any, 
      which means that the default type for all elements is dc:SimpleLiteral.

            This is the default type for all of the DC elements.

            Text is allowed because mixed="true", but sub-elements
            are disallowed because minOccurs="0" and maxOccurs="0"
