/**
@class MWspHeaderCodePages
@since			7.0
The MWspHeaderCodePages API provides an interface to a set of header code
pages as defined by the WSP Specification, July 2001. This capability 
associates a page number with a page name. The Server can negotiate the
use of header code page proposed by the Client by including the page codes
(without the page name) in the return negotiation.

The interface allows the set of header code pages to be accessed one by one.
The read function provides the caller with a copy of the header code page 
information. The set can be reset to the default value of the capability (as
defined by the WSP Specification), which is an empty set. A header code page 
can be added to the set.
