permissions -rw-r--r--
Add an export() view, and implement it as text/text for Document. For every Model except Document, the public() view is displayed for any attempts to access the export() view. Currently, the permissions for export() are the same as for public(). This seems reasonable for Document, since anyone could extract the raw HTML from the page source anyway. The permissions should probably be different for other types of exports, such as vCard or iCard exports of profiles, CSV exports of lists, etc. Patch by: Todd Larsen Review by: to-be-reviewed
