External module in the base Suite that names all the external modules (except itself) that are part of the base Suite (Note: This module does not declare itself, the DTD, any of the Journal Publishing customization modules, or the Publishing-DTD-specific Module of Modules which declares the Journal Publishing customization modules.)
A DTD selects from the named modules by referencing the external Parameter Entities defined in the Module to Name the Modules. To include a set of elements (such as all the lists or the MathML elements), a DTD references the external Parameter Entity of the module that contains those elements.
