An inheritable attribute is one that can be passed from one graphical element (such as an Activity or a State) to another one lower in the hierarchy tree. To designate a Design Attribute as “Inheritable,” add its name to the
inheritable_attributes.txt
file, which includes a newline delimited list of “Inheritable Attribute” names. If the file does not exist, create it in the$STM_ROOT\etc\ctd\<osi-name>
directory).
