Description

Since we have full control over what is stored in our indexes, we want to retrieve highlighted terms or phrases in "real" XML-tags ...

<str>
 <em>Napoleon</em> 
</str>

... rather than in escaped sequences:

<str>
 &lt;em&gt;Napoleon&lt;/em&gt; 
</str>

Until now I haven't discovered any solution to solve this problem out-of-the-box. We patched together a very crude workaround involving Cocoon's ServletService, a XSLT-stylesheet and disableOutputEscaping="yes".

Therefore this patch provides:

• a field doEscape in TextResponseWriter and corresponding getters/setters
• support for a request-parameter "escape=off" to disable escaping

I'm not sure if I have chosen the optimal approach to address this issue or if the issue is even a issue. Maybe there is a better way with Formatters/Encoders or something else?
