Content Dictionaries named `math1', `math2' etc., then you should
not name a derived Content Dictionary `mathN' where N is an integer.

<Description>
This is a content dictionary to represent content dictionaries, so
that they may be passed between OpenMath compliant application in a
similar way to mathematical objects.
The information written here is taken from chapter 4 of the current
draft of the "OpenMath Standard".

<Description>
This symbol is used to represent the element which contains the
definition of each symbol in a content dictionary. That is: it must
contain a 'Name' element and a 'Description' element, and it may contain
an arbitrary number of 'Example', 'FMP' or 'CMP' elements.
</Description>
</CDDefinition>
<CDDefinition>
<Name> CDName </Name>
<Role>application</Role>
<Description>
An element which contains the string corresponding to the name of the CD.
The string must match the syntax for CD names given in the OpenMath
Standard. Here and elsewhere white space occurring at the beginning or
end of the string will be ignored.
</Description>
</CDDefinition>
<CDDefinition>
<Name> CDURL </Name>
<Role>application</Role>
<Description>
An optional element.
If it is used it contains a string representing the URL where the
canonical reference copy of this CD is stored.
</Description>
</CDDefinition>
<CDDefinition>
<Name> Example </Name>
<Role>application</Role>
<Description>
An element which contains an arbitrary number of children,
each of which is either a string or an OpenMath Object.
These children give examples in natural language, or in OpenMath, of the
enclosing symbol definition.
</Description>
</CDDefinition>
<CDDefinition>
<Name> CDDate </Name>
<Role>application</Role>
<Description>
An element which contains a date as a string in the ISO-8601
YYYY-MM-DD format. This gives the date at which the Content Dictionary
was last edited.
</Description>
</CDDefinition>
<CDDefinition>
<Name> CDVersion </Name>
<Role>application</Role>
<Description>
An element which contains a version number for the CD.
This should be a non negative integer. Any change to the CD
that affects existing OpenMath applications that support this CD
should result in an increase in the version number.
</Description>
</CDDefinition>
<CDDefinition>
<Name> CDRevision </Name>
<Role>application</Role>
<Description>
An element which contains a revision number (or minor version number)
This should be a non-negative integer starting from zero for each
new version. Additional examples would be typical changes
to a CD requiring a new revision number.
</Description>
</CDDefinition>
<CDDefinition>
<Name> CDReviewDate </Name>
<Role>application</Role>
<Description>
An element which contains a date as a string in the ISO-8601
YYYY-MM-DD format. This gives the date at which the Content Dictionary
is next scheduled for review. It should be expected to be stable
until at least this date.

<Name> CDStatus </Name>
<Role>application</Role>
<Description>
An element giving information on the status of the CD.
The content of the element must be one of the following strings.
