[Standards-JIG] JEP-0060 Publisher Model - node hirarchy permissions

[bernhard]

I have some questions about jep-0060 publisher model:

1.) Is there a possibility to grant node creation to publishers?
2.) A collection is similar to a directory in file system - do we need that?
3.) Is it possible to grant write access to all nodes of a collection?
4.) If it is possible for a publisher (not owner) to create a new node - 
who is the owner of the new node?
5.) If it is not possible for for a publisher to create new nodes - 
isn't that a limitation that should not be?
