@rw-access @andrewstucki @paulewing This field would remove the need for wildcards on file attributes.

Currently file.mode is a field that only makes sense in posix environments. With a bit more work (not currently reflected in the def), we could map that posix bit field to a predictable set of values for file.attributes. E.g. world-read, world-write, world-executable, group-read, etc.

I think file.attributes would be a better way to capture the attributes of a file, independent of platform.

Ok, I don't want to over-complicate this, so I think I'll merge as is.

Let's leave out the Posix mapping of the octal attributes for now, as this could lead to more questions, such as exact naming, and additional selinux/apparmor attributes. But this is definitely something we should dig into later.

I'll open the follow-up issue and merge this one.
