modifierExtension property
modifierExtension
May be used to represent additional information
that is not part of the basic definition of the resource and that
modifies the understanding of the element that contains it and/or the
understanding of the containing element's descendants. Usually
modifier elements provide negation or qualification. To make the use
of extensions safe and managable, there is a strict set of governance
applied to the definition and use of extensions. Though any
implementer is allowed to define an extension, there is a set of
requirements that SHALL be met as part of the definition of the
extension. Applications processing a resource are required to check
for modifier extensions.Modifier extensions SHALL NOT change the
meaning of any elements on Resource or DomainResource (including
cannot change the meaning of modifierExtension itself).
