You still need the custom action, because the File table's Attributes column
does not support clearing the Archive attribute.
I don't think this is a particularly common thing to do - for the reasons I
explained earlier - so do not think it justifies complicating the compiler,
the custom actions, and the documentation. Specifically, the OS will
automatically set the Archive bit when installing a new file anyway. If you
clear the flag after installing the file, the file will not be backed up on
the next incremental or differential backup, which will very much surprise
system administrators, and could cause your software not to work correctly
if the system has to be restored from the last full backup plus a
differential or a sequence of incrementals (because a critical file or
change to a critical file was not captured in the backup). On the whole I
don't think it's a good thing to do.

This brings up a question that occurs to me fairly regularly reading this
list and that is is it hard to be a contributor to the wix effort and/or
does it take a long time to see contributed changes become available?
This seems like the kind of candidate question where it'd be nice to
recommend Lorne (if willing) add support for Archive to the <File> tag
instead of doing the work in a custom action.
Also a good time for another shout out to Rob/Bob and all the rest for all
the great work and great support/help they do/give. We seem to have burdened
so few with so much on this project.
One more thing I've been curisous about is is there much interest among the
readers here in springing up an effort to add external UI to this project.
I've been contemplating what it would be like to be able to define the UI in
html/xaml.

It's a strange requirement and you'll have to use a CustomAction. You might
look at the secureobj.cpp code to see how best to do that since SecureObj
can change things that were just installed. Non-trivial amount of work to
do correctly.

Thanks Mike. I'm not using the attribute directly, but I do need to be
able to clear or set it. This is for an internal project so I'm not sure
what I can say publically, but one of the requirements is control over
all of the destination file attributes.
