  54  * "wbxml_map[]" array.
  55  *
  56  * NOTES:
  57  *
  58  *  - Code page switches only apply to the following token. In the WBXML/1.x
  59  *    ABNF notation, it can be proven that the switch_page can only precede
  60  *    the following tokens:
  61  *      o  stag      : TAG | LITERAL | LITERAL_A | LITERAL_C | LITERAL_AC
  62  *      o  attr      : ATTRSTART | ATTRVALUE
  63  *      o  extension : EXT_I | EXT_T | EXT
  64  *    Code page switches are displayed in a separate column. The only allowed
  65  *    code page switches are from code page 0 to another codepage (by means of
  66  *    a SWITCH_PAGE token), and from this other code page back to code page 0
  67  *    (this happens automatically).
  68  *
  69  *  - In order to render the XML content, recursion is inevitable at some
  70  *    point (when a tag with content occurs in the content of a tag with
  71  *    content). The code will however not recurse if this is not strictly
  72  *    required (e.g., tag without content in the content of a tag with
  73  *    content).
  74  *
  75  *  - I found it useful to display the XML nesting level as a first "column",
  76  *    followed by the abbreviated WBXML token interpretation. When a mapping
  77  *    is defined for the parsed WBXML content, then the XML rendering is
  78  *    displayed with appropriate indentation (maximum nesting level = 255,
  79  *    after which the nesting and level will safely roll-over to 0).
  80  *
  81  *  - The WAP Forum defines the order of precedence for finding out the
  82  *    WBXML content type (same rules for charset) as follows:
  83  *      1. Look in the Content-Type WSP header
  84  *      2. Look in the WBXML header
  85  *    Currently there is no means of using content type parameters:
  86  *      o  Type=<some_type>
  87  *      o  Charset=<charset_of_the_content>
  88  *    So it is possible some WBXML content types are incorrectly parsed.
  89  *    This would only be the case when the content type declaration in the
  90  *    WSP Content-Type header would be different (or would have parameters
  91  *    which are relevant to the WBXML decoding) from the content type
  92  *    identifier specified in the WBXML header.
  93  *    TODO: investigate this and provide correct decoding at all times.
