<!-- ============================================================= -->
<!-- ============================================================= -->
<!-- SYSTEM: Archiving and Interchange DTD Suite -->
<!-- -->
<!-- PURPOSE: Names all elements in the math classes -->
<!-- -->
<!-- CONTAINS: 1) Default definition of the math classes -->
<!-- 2) Inline formula <inline-formula> -->
<!-- 3) Display Formula <disp-formula> -->
<!-- 4) TeX Math Equation <tex-math> -->
<!-- -->
<!-- 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." -->
<!-- -->
<!-- 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. -->
<!-- -->
<!-- Suggestions for refinements and enhancements to -->
<!-- the DTD suite should be sent in email to: -->
<!-- archive-dtd@ncbi.nlm.nih.gov -->

Version Reason/Occasion (who) vx.x (yyyy-mm-dd)
=============================================================
Version 3.0 (DAL/BTU) v3.0 (2007-10-31)
Version 3.0 is the first non-backward-compatible release.
In addition to the usual incremental changes, some
elements and attributes have been renamed and/or remodeled
to better meet user needs and to increase tag set consistency.
All module change histories are available through the Tag Suite
web site at http://dtd.nlm.nih.gov.
Details on version 3.0 are available at
http://dtd.nlm.nih.gov/3.0.
