docs: Transforms the current value into a parameter map.<p>
  
  The current value must be a nested content with sub-values that
  have exactly 2 values each, for example like this:<p>
  
  <pre>
  &lt;Parameters&gt;
  &lt;Key&gt;&lt;foo&gt;&lt;/Key&gt;
  &lt;Value&gt;&lt;bar&gt;&lt;/Value&gt;
  &lt;/Parameters&gt;
  &lt;Parameters&gt;
  &lt;Key&gt;&lt;foo2&gt;&lt;/Key&gt;
  &lt;Value&gt;&lt;bar2&gt;&lt;/Value&gt;
  &lt;/Parameters&gt;
  </pre>
  
  Please note that the result Map is a simple String map,
  NOT a map with {@link CmsJspContentAccessValueWrapper} classes.<p>
  
  @return the current value transformed into a parameter map
