* WBXML token components 

*

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

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

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

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

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

* the token is in attribute or tag code space.

* 

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

* wbxml spec defines further subsets of bits for tags

* and attributes. The parser itself only int32erprets 

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

* token value lookups in dictionaries.
