We should be able to reference a phragment document into a phriction wiki document.
**Example**
Please download this [[ https://secure.phabricator.com/phragment/browse/Test | phragment document ]] and place it into your working directory.
To do that I had to specify the whole URL (https://secure.phabricator.com/phragment/browse/Test) to the phragment but it could be nice to directly write something like {P4162 | phragment document} instead.
