In the argument list, items represent OCG/OCMD ids as well as nested Boolean
functions. As nesting of the three functions is possible, any thinkable
-visibility relationship can be defined. Note that `\Not{...}' accepts only one

+visibility relationship can be defined.
-As a trivial example, the visibility expression equivalent of the policy
-directive `\AllOff{...}' is written as `\Not{ \Or{ ... } }'.
+Note that `\Not{...}' accepts only one item, either an OCG/OCMD id or a nested
+function. Besides that, a single, isolated OCG/OCMD item is not allowed as an
+expression, it must always be embedded in one of the Boolean functions listed
+above. In the simple case of an OCMD depending on a single OCG in a positive
+way, it is better to use a policy, such as `\AllOn{<OCG id>}', or to put it as
+`\And{<OCG id>}'.
+
+Thus, simple OCMD visibilities can be expressed in an equivalent way by a
+policy or an expression. For example, the visibility expression equivalent of
+the policy directive `\AllOff{...}' is written by means of Boolean functions as
+`\Not{ \Or{ ... } }'.
+
+Note that Boolean functions and policy directives cannot be intermixed.
