Marcel,
Great!
This is as I suspected but I wanted to make sure! Like I said the spec is
not entirely clear to me on this.

this depends what you intend to do with those publications and what
requirements you have. certain features are not cross-workspace. e.g.
references are only possible between nodes of the same workspace.
executing a query will always be targeted to a single workspace.

you can look at workspaces as local checkouts of a revision control
system. those checkouts are not all the same. one may only contain a
subset of the items that are under revision control, another may contain
revisions of items that are tagged to a certain milestone. and then you
may see items in a checkout that are not even under version control. all
of this also applies to JCR workspaces.

different workspace may checkout different version of the 'same node'.
thus the content of the nodes are different, but they belong to the same
version history.

no, changes to nodes are strictly workspace local. to get the changes
into another workspace you either have to:
- clone the node across workspaces
or
- check in the changes and then update the node in the other workspace
to the just checked in version.
