If I use scheme A on a system that only supports scheme B, I'll have to convert to scheme B first, which will be lossy. I agree it would be a nice goal to have a platform independent syntax, but I just don't see it working well. Aren't be better including platform-dependent ACL support rather than no support? -- David
