Getting warmer. How about:
* ACTUAL is the tree on the local disk, ignoring Subversion
administrative directories, and regarding every node as having
no Subversion properties.
(Note that we might want to consider variations such as
"... having no Subversion properties except for 'svn:executable' set
to '*' iff the node's executable-by-owner permission is set."
"... except as defined by the user's auto-props configuration."
"... excluding nodes with the operating system's 'hidden' flag set."
)

I was also questioning the intent of defining WORKING as a tree that has
the BASE file contents. That seems silly: what useful concept does that
represent? It seems to me that it represents an implementation artifact:
the set of modifications that Subversion records explicitly in its
meta-data rather than the modifications that Subversion scans for
dynamically. That's not a distinction of much interest to the higher
layers of software.
I submit that it is much more sensible to define WORKING as I suggested
in my earlier mail. (i.e. having the disk file contents)
