#### 8.1.3 Pragma Declared Pure

This pragma is not specific to the Distributed Systems Annex. A pure package can appear in the context of any package, categorized or not. A pure package is a preelaborable package that does not contain variable data. It is particularly useful to define types, constants and subprograms shared by several categorized packages. In contrast, normal packages cannot appear in the context of categorized package declarations. Because a pure package has no state, it can be duplicated on several partitions.
