Thanks for the reply, but I don't think I made myself clear.
The tour will be initially 60 or so panoramas that are separate, each of which will be launched from my Google Map interface.
This is quite a simple thing to so, since all I need is to Flashificate 60 individual panoramas.
However, I shall be using a uniform skin throughout, so there will be elements of each that will remain constant. The problem this brings to mind is the same as I found with the Røros tour, since if I want to change one single aspect of the skin or its functions, then I will need to do that 60 (or as in the case of Røros 101) times. This is a pain . . .
If all the skin elements and functions are contained in a master xml file, which is then imported to each individual xml, when such changes occur, it should be easy (lol) enough to just change the master file and everything else follows suit.
The question (I am not a programmer) I ask is how to achieve that import.
