No, you said that if there would more than 1 set of --s, 
then the name would be the original name and the namespace would
be content.

What ids are legal is a matter of policy enforced by the add component.
People could install an alternate add component that enforced a more
restrictive naming policy, such as one like Zope 2's (e.g. Disallow
a name if there is a view of the same name). Some people might just
be willing to take their chances. The current container traverser will
look for a view if an item can't be found.

Fair enough. Really general views will need to use the full syntax.
