     The copyright holder grants you permission to redistribute this 
     document freely as a verbatim copy. Furthermore, the copyright
     holder permits you to develop any derived work from this document
     provided that the following conditions are met.
       a) The derived work acknowledges the fact that it is derived from
          this document, and maintains a prominent reference in the 
          work to the original source.
       b) The fact that the derived work is not the original OpenMath 
          document is stated prominently in the derived work.  Moreover if
          both this document and the derived work are Content Dictionaries
          then the derived work must include a different CDName element,
          chosen so that it cannot be confused with any works adopted by
          the OpenMath Society.  In particular, if there is a Content 
          Dictionary Group whose name is, for example, `math' containing
          Content Dictionaries named `math1', `math2' etc., then you should 
          not name a derived Content Dictionary `mathN' where N is an integer.
          However you are free to name it `private_mathN' or some such.  This
          is because the names `mathN' may be used by the OpenMath Society
          for future extensions.
       c) The derived work is distributed under terms that allow the
          compilation of derived works, but keep paragraphs a) and b)
          intact.  The simplest way to do this is to distribute the derived
          work under the OpenMath license, but this is not a requirement.
     If you have questions about this license please contact the OpenMath
     society at http://www.openmath.org.

A CD of alternative encoding symbols

This CD is motivated in part by a desire to maintain compatibility with the MathML semantics element,

In order for it to be possible for OpenMath to express symbols in an alternative encoding (this facilitates the exact translation and representation of objects) we use the OpenMath attribution nodes (which performs a similar role to the MathML semantics nodes). The formats and descriptions of common syntaxes are held in this CD; at present this only includes LaTeX and MathML. 

Alternative encodings in OpenMath are dealt with by using OMATTR
symbols together with the alternative encoding placed in a string.
The string encoding must be valid XML, and so non-XML valid characters
must themselves be encoded as suggested in "Draft of the OpenMath
Standard".

For alternative encodings to be represented in OpenMath, one must
define a symbol to describe the encoding.

MathML_encoding

Role:
attribution
Description:

A symbol which heads a piece of MathML encoding in an attribution. The MathML encoding is an XML encoding, and the details may be found at: http://www.w3.org/Math/Overview.html

Example:
sin ⁡ ( 1.5 )
Example:
1 + 2
