  22  /**
  23  * 
  24  * This class implements a Text_Wiki_Rule to include the results of a
  25  * script directly into the source at parse-time; thus, the output of the
  26  * script will be parsed by Text_Wiki.  This differs from the 'embed'
  27  * rule, which incorporates the results at render-time, meaning that the
  28  * 'embed' content is not parsed by Text_Wiki.
  29  *
  30  * This rule is inherently not secure; it allows cross-site scripting to
  31  * occur if the embedded output has <script> or other similar tags.  Be
  32  * careful.
