Classe: Text_Wiki_Parse_Embed  - X-Ref

This class implements a Text_Wiki_Parse to embed the contents of a URL
inside the page at render-time.  Typically used to get script output.
This differs from the 'include' rule, which incorporates results at
parse-time; 'embed' output does not get parsed by Text_Wiki, while
'include' ouput does.

This rule is inherently not secure; it allows cross-site scripting to
occur if the embedded output has <script> or other similar tags.  Be
careful.
