The Library editor can display two types of settings for each element:
Global settings. Properties that apply to all instances of an element. If the same element is defined in multiple contexts of the message, editing the global settings affects all the instances.
Positional settings. Properties that apply to a single definition of the element in the message. Editing the positional settings affects only the message context that you have selected in the Library editor.
In the HIPAA library, for example, a global setting might permit an element to contain any of 10 enumerated values. A positional setting might limit the same element to a subset of two values.
