* Simple implementation of {@link Stax2BlockSource} that encapsulates
* an char array.
*
* Note that no copy is made of the passed-in array, and that further
* there are direct access methods. Thus, although callers are not
* to modify contents of returned array, this can not be guaranteed;
* and as such if this would be a problem (security problem for example),
* caller has to make a copy of the array and pass that copy to the
* constructor.
