Wildcard attributes

What I really love in the new versions of FME is the 'Attribute Tree'.This occurs if you place a .(dot) into a attribute name.It is a great way to group attributes (from different streams) into sub groups.

For example in this project I have global parameters that are generated in the beginning and used in every feature.

If I create anewattribute before this transfomer, all AttributeKeepers need to be adjusted.It would really help to wildcard these groups, because I know I need all my "global." attributes.

So a small toggle on the main group with 3 modes:

- empty (no childs)

- block (some childs)

- circle?keep all childs, without having to reselect when a new one is added to the group

The last option would be a dynamic selection.For example: keep all "_global.*" attributes
