The cache statement allows some control over the cache feature of the DIML engine (v3.0).

Whatever the syntax used, the cache statement has no effect on cached copies (should even never appear in cached document).

on : Activates caching from that location, i.e., allows static resolution of the following statements.

off : Disables caching, i.e., avoid statements being resolved in the cache copy. The dynamic statements will remain unresolved in the cached copy.

clear : Clears the cache, deleting all cache resources (including cache hash).
