The files in this directory are DTD fragments specifying entities required for MathML. Mainly these are for mathematical symbols and are declared as CDATA entities giving the unicode position.
The files were mainly automatically generated from the HTML tables given in the MathML recommendation, with some hand correction.
The conversion script and the conversions themselves are copyright 1998 NAG and the OpenMath Consortium, as given in the comments in the files. The files themselves may be freely used as long as the copyright notice is preserved.
Most of the files were generated from the `extended' tables in which the ISO names have been augmented with MathML aliases. The Emacs Lisp file used for conversion is also available.
