[xml] does libxml never touch _private field of struct?

Hi.

$ grep _private *
entities.h:    void           *_private;                /* application data */
parser.h:    void              *_private;      /* For user data, libxml won't touch it */
schemasInternals.h:    void *_private;  /* unused by the library for users or bindings */
tree.h:    void           *_private;            /* application data */
tree.h:    void           *_private;            /* application data */
tree.h:    void           *_private;   /* application data */
tree.h:    void           *_private;    /* application data */
tree.h:    void           *_private;    /* application data */
tree.h:    void           *_private;    /* application data */
tree.h:    void           *_private;    /* application data */

you mean all those _private field of structs are unused by libxml?
