## Hierarchy
Groups can be children of another group. Members of children groups are effective members of the parent group.
When you bind a group to an application or flow, any members of any child group of the selected group will have access.
Recursion is limited to 20 levels to prevent deadlocks.
## Attributes
Attributes of groups are recursively merged, for all groups the user is a _direct_ member of.
