Dependencies to special versions

Hi,

I have a problem with dependencies in some of my packages:

There is a "task" package which just depends on the concrete version  
of the children. It looks like this:

- - debian/contrl -----------------------
Package: foo
Depends: foo-doc (= ${Source-Version}), foo-misc (= ${Source-Version})
...

Package: foo-misc
Depends: ${shlibs:Depends}
...

Package: foo-doc
...
- --------------------------------------------

When I have installed an old version, say foo-1.0-1 and its children 
with the same version, foo will depend on foo-doc-1.0-1 and 
foo-misc-1.0-1.

Now I create a new version 1.0-2 of all packages and try to upgrade. 
apt-get will download the files and unpacks them. Before 
configuration of foo-1.0-2 it complains that foo-doc and foo-misc are 
not installed in the newer version. Moreover it can't upgrade them 
because it would break the dependency of the installed foo-1.0-1.

My theory is that this kind of dependencies is insane, because on 
update there is no way to upgrade everything in an atomic action 
which would be necessary to keep all dependencies working all the 
time. Is this correct?

The work around/fix I imagine is to just depend on the package without 
any revision or use something like 

Depends: foo-doc (>= ${Source-Version}), foo-misc (>= 
${Source-Version})

Is this correct or how would I solve a 1-1 relation between several 
packages?

Thnx in advance
