	'xmlNodePtr' is a typedef, so the prototype now say "the pointer 
'node' is non modifiable; the data pointed by 'node' are modifiable".
	If i'm not wrong, obviously.
	If 'xmlNodePtr' were a macro (thanks Rush), the things would be 
different.
	I don't speek a good english, so it is very difficult
for me to express what i mean. Sorry for this.
	My doubt is: what is the intent? What should be costant?
	The pointer 'node'?
	The data pointed by 'node'?
	Both?
	I suppose the data pointed by 'node' or both, non only the 
pointer.
