Using Special Characters and Non-Unique Element Names in an Area Definition
You can use the syntax 'dimensionname':'elementname' in
an area definition to specify elements that are not unique to a single
dimension or for dimension names that contain special characters.
For example, the area
['Units', 'Mar', 'Region':'North America']lets you write a statement when the element North America is not unique to the Region dimension.
Similarly, the area
['}Groups':'ADMIN'] allows you to write a statement for the }Groups dimension, which contains the curly brace } special character.
