Gets the tag ready to parse a new sdl tree by resetting the depth and the line number.
It is unnecessary to call this before parsing the first sdl tree but would not be harmful.
It does not reset the namespace/name/values/attributes because those will
be reset by the parser on the next call to parseAsonTag when it calls resetForNextTag().
