A proposition, which may be assigned a truth value in a given
context. Precisely, it is a well-formed formula (Wff) using the rules
described in the Wff production. A proposition is used in the
inform communicative act (CA) and other CAs derived from it.
An action, which can be performed. An action may be a single
action or a composite action built using the sequencing and
alternative operators. An action is used as a content expression
when the act is request and other CAs derived from it.
An identifying reference expression (IRE), which identifies an
object in the domain. This is the Referential operator and is used
in the inform-ref macro act and other CAs derived from it.
