beware, scantokens adapts to the current catcode regime; when a macro is
loaded it's kind of frozen, so then a \ is still a \, while in xml mode,
the \ is something different, so here scantokens would read the data as
being xml (unless xml mode is temporary disables).
I guess that this fuzzy explanation will make you go into the tex source
