Coordinate system domain Domain
The Domain attribute also controls how a Frame behaves when it is used (by
astFindFrame) as a template to match another (target) Frame. It does this by specifying
the Domain that the target Frame should have in order to match the template. If the
Domain value in the template Frame is set, then only targets with the same Domain value
will be matched. If the template’
s Domain value is not set, however, then the target’
s Domain will be ignored.
