* CUR returns the current xmlChar value, i.e. a 8 bit value if compiled
* in ISO-Latin or UTF-8, and the current 16 bit value if compiled
* in UNICODE mode. This should be used internally by the parser
* only to compare to ASCII values otherwise it would break when
* running with UTF-8 encoding.
* NXT(n) returns the n'th next xmlChar. Same as CUR is should be used only
* to compare on ASCII based substring.
* UPP(n) returns the n'th next xmlChar converted to uppercase. Same as CUR
* it should be used only to compare on ASCII based substring.
* SKIP(n) Skip n xmlChar, and must also be used only to skip ASCII defined
* strings without newlines within the parser.
*
* Clean macros, not dependent of an ASCII context, expect UTF-8 encoding
