No backward-incompatible changes. Archiving loosened even more. New structures for all the DTDs. 6. Updated public identifier to "v2.3 20070202//EN" ============================================================= 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 5. 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 4. SCHEMA - added the "xsi" prefix and namespace FIXED declaration here, because them MathML DTD (in the module mathml2-qname-mod.ent) let this namespace be defaulted to CDATA although they set up for the FIXED value. We needed the real FIXED value for the schema version of these DTDs. 3. Updated public identifier to "v2.3 20070202" ============================================================= 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 "v2.3 20070202" ============================================================= 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 UP FOR THE MathML MODULE --> <!-- ============================================================= --> <!-- MathML DTD --> <!-- The official version of the MathML 2.0 can be found at: http://www.w3.org/TR/MathML2/ See also Mathematical Markup Language (MathML) Version 2.0 A.
