Could it be because it's still flawed...? :wink:

If the separation is logical, it should be physical (also it's more understandeable). The Local settings can't be on the same file (ie. probably only an user with admin privileges can change it).

Yes, in such a case you cannot use just one file. Anyway, the idea was to have an XML where root was e.g., Settings and its three (or more or less) children were Global, User and Local (may be this not). By using XML and XSLT processors you can then modify each child independently (or not, it depend on what you want to do :)). You can for example look at one MPEG-21 DIA works. From a bitstream a (generic) description (XML-based) is generated. This XML description is successively modified to fit particular constraints (could be modified several times, anyway). At the end the adapted bitstream is re-created from the transformed bistream. All this is possible by using XML/XSLT.

I've never used XSLT transformations, and yes, it's possible, but it can complicate things where it's not necessary.
