atom
Description
Wpart responsible for storing the atoms inside the database.
The user's input is converted to the existing Erlang atom. If there is no such atom inside the Erlang Virtual Machine, validation will fail. The existence assumption has been made because of the security reasons - in order to prevent reaching the maximum number of atoms limit.
The rendered widget is <input type="string" ... />.
