<p>
The domain_error class  is derived from the  logic_error class.  The domain_error class
represents exceptions  that are  occur because  some piece of the software component that
causes the exception is violating some domain specification.   Domain specifications are
implementation  specific and class specific. What constitues a domain error will depend 
on the context in which the error occurs and what types of  attributes, characteristics, 
and behaviors are acceptable in that context.  This  class of exception represents a '
wrong subject matter or wrong content'  violation as opposed to  a 'wrong object type ' 
violation. This class represents a node class and  can therefore be used as a base class 
for user defined classes. The current version of the C++ standard  does not require any method
in the standard C++ classes to throw  and exception  class domain_error.

<h3>Description</h3>
<p>
The domain_error() method constructs an object of type domain_error.  The What_Arg parameter
can be used to set a description of the kind of error that this exception represents. 
A set possible solutions is sometimes supplied with the exception description in addition
to the type of error.
