This new version adds the `ocmd' environment: \begin{ocmd}[<OCMD id>]{[<visibility policy>][,<visibility expression>]} ... material to be put on a PDF layer ... \end{ocmd} An OCMD (Optional Content Membership Dictionary) is a PDF Layer whose visibility is calculated from other OCGs current visibility states according to a visibility policy and/or a visibility expression. A visibility policy is defined by choosing one of the directives \AllOn{<OCG id 1>, <OCG id 2>, ...} \AnyOn{<OCG id 1>, <OCG id 2>, ...} \AnyOff{<OCG id 1>, <OCG id 2>, ...} \AllOff{<OCG id 1>, <OCG id 2>, ...} A visibility expression is much more flexible than a policy. Arbitrarily complex visibility relationships can be formulated, based on the Boolean functions \And{<item a>, <item b>, ...} \Or{<item i>, <item j>, ...} \Not{<item n>} In the argument list, items represent OCG ids and nested Boolean functions. As nesting of the three functions is possible, any thinkable visibility relationship can be defined.
