Description

Currently, when connecting a link to a zone, you bind the zone parameter of the link to the client-side id of the Zone.

To do this, you must know the client-side id of the Zone.

It would be nice if the zone value could be evaluated on the client and make use of the rendered DOM to simplify this.

I thought the special string "^" could mean "the containing Zone", and could be located via the "t-zone" CSS class that Zones normally have.

An extended form could be "^.foo" to find an enclosing element with CSS class foo and assume that is the zone (this would help when dealing with nested zones).

The exact syntax is up for debate but the idea is that the connection could be made on the client-side without having to deal with the (relative) intricacies of either assigning a zone id explicitly, or reading the Zone's id.
