PI EF security trait/context

We are trying to standardize and mutualize all of our templates but we want to keep the security well defined : in general it work perfectly when things are in read only mode.

Where write access is needed everything looks good for Elements since the security is redefined for each tree node.

But when we are working with event frame it is a big mess because the security is derived from template :

• We cannot use a single event frame template that have exactly the same logic for all the site but security context different.

• We don't want to have user writing to elements, but just to a specific attribute in the event frames not all.

a good improvement would be to define the security settings for ef template but add one additional layer :

• EF context security : we can define one per site: and for a specific element depending on the value of this security context the security of all the EF generated by analysis have this security layer applied.

This idea would be applicable to aknowledgment but also attribute edition, and all other rights

I know there is the possibility to create child template per site : but it is not like this that we would push end user to standardize and rationalize the number of templates.
