Description

A Symbol is a name that represents a value. It should be used in contexts in which the name will actually be replaced by a value before processing. The canonical example is a #defined symbol in a C program where the C preprocessor replaces every occurance of the symbol with its value before compilation begins.

The Limit value of the Class attribute identifies those symbols that represent system limitations (for example, the number of characters allowed in a path name or the largest possible positive integer). DocBook V3.1 introduced the Constant element, which may be more suitable for some of these symbols.
