(http://extensions.xwiki.org/xwiki/bin/view/Extension/Output+JSON) , it's possible to
allow such content by including request parameters xpage=plain and outputSyntax=plain.
However, this approach requires all pages that refer to the script to remember to include
these parameters, which is rather error prone.

Vincent replied:
Yes, there is :)
For Groovy, see http://extensions.xwiki.org/xwiki/bin/view/Extension/Script+Macro
(check the output and wiki parameters)
For Velocity, see http://extensions.xwiki.org/xwiki/bin/view/Extension/Velocity+Macro
(same parameter names).
OK, so trying both options with a content body
{{velocity output="false" wiki="false"}}
$response.setContentType('application/json')
{
"greeting" : "Hello",
"location": "World"
}
{{/velocity}}
I get a document of Content-Script-Type text/javascript but with a 38KB file of HTML
containing the usual Wiki page content, which I'd like to avoid. I think if I
explicitly set xpage=plain in the request then the template skips rendering this stuff,
but what I was wondering was whether I could set this from within my script instead.
