[xml] xmlNewNs

[Laurent Marzullo <laurent marzu org>]

Hello,

I've notice that "xmlNewNs" does not delete the string I gave it. So, as 
my prefix is a newly created one (with xmlStrndup) I would like to know 
if there's a way
to "register" this string as to be deleted at document deletion time or 
if I should take care of it myself ?

thanks you very much all
