+Preliminary DTD for Open JPEG "mj2_to_metadata" function.
+Last revised: April 20, 2005
+Author: Glenn Pearson, at U.S. National Library of Medicine.
+See mj2_to_metadata.c regarding copyright, license, disclaimer status.
+
+While the vocabulary of this DTD is based on the relevant portions of the
+ISO/IEC JPEG 200 standard, the detailed representation is the author's own.
+It is neither an ISO/IEC nor NLM official or consensus representation.
+Furthermore, it deviates from a pure representation of the ISO/IEC standard
+in these aspects:
+
+ - it is incomplete in a number of ways (which to some extent may be
+ addressed over time);
+ - it has extensions for "derived" data and "statistics";
+ - it is more flexible. That is, some elements are marked as optional
+ not because they are optional in an MJ2 file, but because reporting
+ of them is optional based on current or projected mj2_to_metadata
+ command-line flags.
