Subversion doesn't have "file revisions." Revision 65 *does* exist,
and File-1 *does* exist in that revision - it just wasn't changed
then, so it looks identical to File-1 in revision 64.

Each revision number represents the state of the entire repository at
that moment in time. If File-1 wasn't changed in revision 65, File-1 @
r65 will look identical to File-1 @ r64.

From your description (but I'm having a hard time understanding what
you're trying to achieve), Subversion may not be the right tool for
your requirements, or may require some significant layering of other
programs/scripts on top of it to get it to do what you want.

A "complex tag" may get you closer to where you want to be. See
http://svnbook.red-bean.com/en/1.5/svn.branchmerge.tags.html#svn.branchmerge.tags.mkcomplex

Not sure what you're trying to do with "baselines" - is this for
detecting changes to items in (for example) a production environment?
That would be a better task for something like Tripwire.
