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