    62 * WBXML token components 

    63 *

    64 * The wbxml parser stores tokens as 32 bits. The meaning

    65 * of each token is determined as a 4-tuple:

    66 * the token itself (8 bits), the code page (8 bits),

    67 * the dictionary in which it is defined (for which we

    68 * allocate 15 bits) and a state flag that indicates whether

    69 * the token is in attribute or tag code space.

    70 * 

    71 * Within the lowest 8 bits (the token component) the

    72 * wbxml spec defines further subsets of bits for tags

    73 * and attributes. The parser itself only int32erprets 

    74 * the lowest 8 bits. The remaining bits are used for

    75 * token value lookups in dictionaries.
