<!-- EXCHANGE TABLE MODEL DECLARATION MODULE -->

<!-- This set of declarations defines the Exchange Table Model as of the
     date shown in the Formal Public Identifier (FPI) for this entity.

     This set of declarations may be referred to using a public external
     entity declaration and reference as shown in the following two lines:

<!ENTITY % calstbls PUBLIC "-//OASIS//DTD Exchange Table Model 19960430//EN">
%calstbls;

     If various parameter entities used within this set of declarations
     are to be given non-default values, the appropriate declarations
     should be given before calling in this package (i.e., before the
     "%calstbls;" reference).

     NOTE:  This set of declarations assumes a NAMELEN of 32 as is used in
     the standard CALS defined SGML declaration.
-->

<!-- This entity includes a set of element and attribute declarations
     that partially defines the Exchange table model.  However, the model
     is not well-defined without the accompanying natural language
     description of the semantics (meanings) of these various elements,
     attributes, and attribute values.  The semantic writeup, also available
     from OASIS, should be used in conjunction with this entity.
-->

<!-- In order to use the Exchange table model, various parameter entity
     declarations are required.  A brief description is as follows:

     This set of declarations will use the default definitions shown below
     for any of these parameter entities that are not declared before this
     set of declarations is referenced.
-->

<!-- These definitions are not directly related to the table model, but are
     used in the default CALS table model and may be defined elsewhere (and
     prior to the inclusion of this table module) in the referencing DTD. -->

<!ENTITY % bodyatt "">
<!ENTITY % yesorno 'NUMBER'  -- no if zero(s),
                                yes if any other digits value -->
<!ENTITY % titles  'title?'>
<!ENTITY % paracon '#PCDATA' -- default for use in entry content -->

<!--
The parameter entities as defined below change and simplify the CALS table
model as published (as part of the Example DTD) in MIL-HDBK-28001.  The
resulting simplified DTD has support from the OASIS vendors and is
therefore more interoperable among different systems.

These following declarations provide the Exchange default definitions
for these entities.  However, these entities can be redefined (by giving
the appropriate parameter entity declaration(s) prior to the reference
to this Table Model declaration set entity) to fit the needs of the
current application.

Note, however, that changes may have significant effect on the ability to
interchange table information.  These changes may manifest themselves
in useability, presentation, and possible structure information degradation.
