<!-- ============================================================= -->
<!-- SYSTEM: Archiving and Interchange DTD Suite -->
<!-- -->
<!-- PURPOSE: Provides the organization for using the -->
<!-- MathML DTD -->
<!-- -->
<!-- CONTAINS: 1) Overrides to standard parameter entities used -->
<!-- in the MathML 2.0 DTD -->
<!-- 2) Call to MathML 2.0 DTD -->
<!-- -->
<!-- MODULES REQUIRED: -->
<!-- 1) mathml2.dtd MathML 2.0 DTD -->
<!-- -->
<!-- CREATED FOR: -->
<!-- Digital archives and publishers who wish to -->
<!-- create a custom XML DTD for original markup of -->
<!-- journal literature, books, and related material, -->
<!-- or for archiving and transferring such material -->
<!-- between archives. -->
<!-- -->
<!-- This DTD is in the public domain. An organization -->
<!-- that wishes to create its own DTD from the suite -->
<!-- may do so without permission from NLM. -->
<!-- -->
<!-- The suite has been set up to be extended using a -->
<!-- new DTD file and a new DTD-specific customization -->
<!-- module to redefine the many Parameter Entities. -->
<!-- Do not modify the suite directly or redistribute -->
<!-- modified versions of the suite. -->
<!-- -->
<!-- In the interest of maintaining consistency and -->
<!-- clarity for potential users, NLM requests: -->
<!-- -->
<!-- 1. If you create a DTD from the Archiving and -->
<!-- Interchange DTD Suite and intend to stay -->
<!-- compatible with the suite, then please include -->
<!-- the following statement as a comment in all of -->
<!-- your DTD modules: -->
<!-- "Created from, and fully compatible with, -->
<!-- the Archiving and Interchange DTD Suite." -->
<!-- -->
<!-- 2. If you alter one or more modules of the suite, -->
<!-- then please rename your version and all its -->
<!-- modules to avoid any confusion with the -->
<!-- original suite. Also, please include the -->
<!-- following statement as a comment in all your -->
<!-- DTD modules: -->
<!-- "Based in part on, but not fully compatible -->
<!-- with, the Archiving and Interchange DTD -->
<!-- Suite." -->
<!-- -->
<!-- Suggestions for refinements and enhancements to -->
<!-- the DTD suite should be sent in email to: -->
<!-- archive-dtd@ncbi.nlm.nih.gov -->
<!-- -->
<!-- ORIGINAL CREATION DATE: -->
<!-- December 2002 -->
<!-- -->
<!-- CREATED BY: Jeff Beck (NCBI) -->
<!-- Deborah Lapeyre (Mulberry Technologies, Inc.) -->
<!-- Bruce Rosenblum (Inera Inc.) -->
<!-- -->
<!-- NLM thanks the Harvard University Libraries, both -->
<!-- for proposing that a draft archiving NLM DTD for -->
<!-- life sciences journals be extended to accommodate -->
<!-- journals in all disciplines and for sponsoring -->
<!-- Bruce Rosenblum's collaboration with other DTD -->
<!-- authors in completing Version 1.0. The Andrew W. -->
<!-- Mellon Foundation provided support for these -->
<!-- important contributions. -->

=============================================================
Version Reason/Occasion (who) vx.x (yyyy-mm-dd)
=============================================================
Version 2.1 (DAL/BTU) v2.1 (2005-06-30)
Changed to MathML 2.0 and MathML 2.0 Character Sets
Added new material requested by NCBI
4. DO NOT INVOKE CHARACTER SETS THROUGH MATHML DTD- Added a new
parameter entity -%mathml-charent.module;, set to IGNORE to
remove the character set invocations from the MathML 2 DTD.
Since that removed both mmlextra and mmlalias at the same time,
invocations to them were added to their modules
3. Updated public identifier to "v2.1 20050630"
=============================================================
Version 2.0 (DAL/BTU) v2.0 (2004-08-30)
Major requirement changes led to the new release, producing
DTD version "2.0":
a) The splitting of the Archival and Interchange Tag Set
DTDs into three DTDs from two: an authoring DTD, an
archive regularization and interchange DTD (the
current Blue Publishing DTD), and a preservationist
archive DTD (the current Green Archiving and Interchange
DTD).
b) AIT Working Group suggestions from the June 04 meeting
and June/July 2004 followup discussions
c) Suite remodularization to meet new (and newly articulated)
modularization requirements
d) New or renamed classes and mixes to make modifications
easier and more consistent
2. Updated public identifier to "v2.0 20040830"
=============================================================
Version 1.1 (TRG) v1.1 (2003-11-01)
1. Added attribute "alternate-form-of" to <mml:math>
(Note: parameter entity %math.qname; resolves to <mml:math>.)
Rationale: Where multiple formats of an item (e.g., graphic
file, media object, chemical structure) are available, this
attribute indicates that a format is a secondary one and
provides a link to the primary format, so that only one
format of an item is displayed.

<!-- Set the "INCLUDE" or "IGNORE" marked section
switch for the MATHML 2.0 DTD. This switch
determines whether the math processing in
the -%mathml.dtd; module or the

will invoke the sets of special characters
that are defined AND INVOKED in the
-%xmlspecchars.ent; module.
A value of "IGNORE" turns off the second
invocation from the MathML DTD. -->

<!-- Because the MATHML invocation is canceled
using the parameter enti6ty just defined,
