Thank you!
I've added a little more info/questions below.

The subcomponents are part of only one component. I would prefer to
have them located inside their respective component. Having them
nested still means that I should let the components refer to their
subcomponents using externals, doesn't it?

This seems doable.

When you do this separate check out, how do you get the changes to the
correct place? Do you test them locally, and check them in before you
copy them to the system structure? I'm completely new to svn, and
rather lost here...
Would careful use of switch be better than externals, or would I just
end up in a big mess?
Or would the trick be to use switch at the moment I would like to do
changes? I.e. I use externals for a complete system, but since
changing in those files would mean that I would be changing tags,
instead of trunks, I should do a switch to the trunk of the
subcomponent?
(And I would need to do a switch on the component level, as well, to
be able to perform feature-commits?)
Branching of systems will not help me, will it? The branch will just
contain the same externals as the system trunk, and since all changes
will be in the subcomponents there will be no connection to the
system, will it?
Shall I both branch and switch?
Is this nesting a bad idea? Or is it normal in larger systems (KDE?)?
