Error messages targetted to the user are kept in the session and are manipulated with the <code>[error]</code> tag. Warnings are manipulated with the <code>[warnings]</code> tag.

This model has the following flaws:

 - By default, the errors are retained in the session. This utterly confuses the user.

 - <code>[error all=1]</code> displays errors in a all but random order. Errors should be displayed in the same order as they appear in the corresponding form.

 - Different semantics of <code>[error]</code> and <code>[warnings]</code>.
