    WBXML Library
    -------------
    
    The WBXML Library (aka libwbxml) contains a library and its associated tools to Parse,
    Encode and Handle WBXML documents.

    The WBXML format is a binary representation of XML, defined by the Wap Forum, and used
    to reduce bandwidth in mobile communications. 
    
    
    Dependency:
    -----------
    
    The WBXML Library needs Expat to enable XML Parsing feature (and so XML to WBXML conversion).
    
    
    High Level API:
    ---------------
    
                        -------------------------
                (1)     |                       |
  [ WBXML ] --------->  |                       | ----------> [ XML ]
                        |     WBXML Library     |
  [ WBXML ] <---------  |                       | <---------- [ XML ]
                        |                       |     (2)
                        -------------------------      
    
    The high level API permits to:
        - (1) Convert a WBXML Document to an XML Document
        - (2) Convert an XML Document to a WBXML Document

    The WBXML Library contains:
        - (1) A WBXML Parser, with a SAX like interface (ie: this is a kind of Expat, but for WBXML)
        - (2) A WBXML Tree structure (an internal representation of a WBXML/XML Document)
        - (3) Libwbxml Callbacks to convert a WBXML Document to a WBXML Tree
        - (4) Expat Callbacks to convert an XML Document to a WBXML Tree
        - (5) A WBXML Encoder, that encodes a WBXML Tree to a WBXML Document or to an XML Document
