Yes, you can. There's a counting scheme that keeps the library from being
initialized more than once. However, the initialization counting scheme is
not thread-safe, so you had better make sure multiple threads don't try to
initialize Xerces-C at the same time.

No, I don't think it will -- it will either be a valid pointer, or 0. Some
investigation on your part could confirm this.
