  <li>noArg - show no input field.</li>
  <li>time - show a JavaScript driven timepicker.<br>
      Example: attr FS20dev widgetOverride on-till:time</li>
  <li>textField - show an input field.<br>
      Example: attr WEB widgetOverride room:textField</li>
  <li>textFieldNL - show the input field and hide the label.</li>
  <li>textField-long - show an input-field, but upon
      clicking on the input field open a textArea (60x25).</li>
  <li>textFieldNL-long - the behaviour is the same
      as :textField-long, but no label is displayed.</li>
  <li>slider,&lt;min&gt;,&lt;step&gt;,&lt;max&gt;[,1] - show
      a JavaScript driven slider. The optional ,1 at the end
      avoids the rounding of floating-point numbers.</li>
  <li>multiple,&lt;val1&gt;,&lt;val2&gt;,..." - present a
      multiple-value-selector with an additional textfield. The result is
      comman separated.</li>
  <li>multiple-strict,&lt;val1&gt;,&lt;val2&gt;,... - like :multiple, but
      without the textfield.</li>
  <li>selectnumbers,&lt;min&gt;,&lt;step&gt;,&lt;max&gt;,&lt;number of
      digits after decimal point&gt;,lin|log10" - display a select widget
      generated with values from min to max with step.<br>
      lin generates a constantly increasing series.  log10 generates an
      exponentially increasing series to base 10, step is related to the
      exponent, e.g. 0.0625.</li>
  <li>select,&lt;val1&gt;,&lt;val2&gt;,... - show a dropdown with all values.
      <b>NOTE</b>: this is also the fallback, if no modifier is found.</li>

=begin html_DE

  <li>noArg - es wird kein weiteres Eingabefeld angezeigt.</li>
  <li>time - zeigt ein Zeitauswahlmen&uuml;.
      Beispiel: attr FS20dev widgetOverride on-till:time</li>
  <li>textField - zeigt ein Eingabefeld.<br>
      Beispiel: attr WEB widgetOverride room:textField</li>
  <li>textField-long - ist wie textField, aber beim Click im Eingabefeld wird
      ein Dialog mit einer HTML textarea (60x25) wird ge&ouml;ffnet.</li>
  <li>slider,&lt;min&gt;,&lt;step&gt;,&lt;max&gt;[,1] - zeigt einen
      Schieberegler. Das optionale 1 (isFloat) vermeidet eine Rundung der
      Fliesskommazahlen.</li>
  <li>multiple,&lt;val1&gt;,&lt;val2&gt;,... - zeigt eine Mehrfachauswahl mit
      einem zus&auml;tzlichen Eingabefeld. Das Ergebnis ist Komma
      separiert.</li>
  <li>multiple-strict,&lt;val1&gt;,&lt;val2&gt;,... - ist wie :multiple,
      blo&szlig; ohne Eingabefeld.</li>
  <li>selectnumbers,&lt;min&gt;,&lt;step&gt;,&lt;max&gt;,&lt;number of
      digits after decimal point&gt;,lin|log10" zeigt ein HTML-select mit einer
      Zahlenreihe vom Wert min bis Wert max mit Schritten von step
      angezeigt.<br>
      Die Angabe lin erzeugt eine konstant ansteigende Reihe.  Die Angabe
      log10 erzeugt eine exponentiell ansteigende Reihe zur Basis 10,
      step bezieht sich auf den Exponenten, z.B. 0.0625.</li>
  <li>select,&lt;val1&gt;,&lt;val2&gt;,... - zeigt ein HTML select mit allen
      Werten. <b>Achtung</b>: so ein Widget wird auch dann angezeigt, falls
      kein passender Modifier gefunden wurde.</li>
