<!– ============================================================= –> <!– 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 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.
                                                                 -->

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
