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.

This CD holds the definitions of the basic universal ("for all")
quantifier and existential ("there exists") quantifier. It is
intended to be `compatible' with the MathML elements representing
these quantifiers.
forall
binder
This symbol represents the universal ("for all") quantifier which takes two
arguments. It must be placed within an OMBIND element. The first argument is the
bound variables (placed within an OMBVAR element), and the second is an expression.
An example to represent the statement for all real x, |sin(x)| <= 1
exists
binder
This symbol represents the existential ("there exists") quantifier
which takes two arguments. It must be placed within an OMBIND element. The first
argument is the bound variables (placed within an OMBVAR element), and the second
is an expression.
An example which represents the statement that there is no solution
to x^n+y^n=z^n for n>2, that is:
it is not true that there exists x,y,z,n | n>2 and x^n+y^n=z^n
