      <para>
       An array that specifies the modifications to make. Each entry in this
       array is an associative array with two or three keys:
       <literal>attrib</literal> maps to the name of the attribute to modify,
       <literal>modtype</literal> maps to the type of modification to perform,
       and (depending on the type of modification) <literal>values</literal>
       maps to an array of attribute values relevant to the modification.
      </para>
      <para>
       Possible values for <literal>modtype</literal> include:
       <variablelist>

         <listitem>
          <para>
           Each value specified through <literal>values</literal> is added (as
           an additional value) to the attribute named by
           <literal>attrib</literal>.

         <listitem>
          <para>
           Each value specified through <literal>values</literal> is removed
           from the attribute named by <literal>attrib</literal>. Any value of
           the attribute not contained in the <literal>values</literal> array
           will remain untouched.

          <para>
           All values are removed from the attribute named by
           <literal>attrib</literal>. A <literal>values</literal> entry must
           not be provided.
