A.2. Nonstandard parsing within the admin interface
Parsing of content via the specialized [regenerate] usertag included with the administrative interface does not obey the above order. The MV_AUTOLOAD and '<!--[tagname]-->' escapes are skipped. There are some other more subtle differences as well; in the very unlikely event that you need to check this in the source code, compare the 'interpolate_html' and 'cache_html' routines in Interpolate.pm.
