    Comments

    Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element.

      Comments

      Some purely arbitrary lists do not have a common subject, so this is optional. Lists having multiple subjects may raise challenges for systems that base access control or other security considerations on linkages to 'subject'. E.g. if a List is associated with multiple Patient subjects, then it would be nominally part of multiple patient compartments, which might drive access rights.

      Comments

      The various reasons for an empty list make a significant interpretation to its interpretation. Note that this code is for use when the entire list has been suppressed, and not for when individual items are omitted - implementers may consider using a text note or a flag on an entry in these cases.

      Comments

      Contained resources do not have a narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied).

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).

        Some purely arbitrary lists do not have a common subject, so this is optional. Lists having multiple subjects may raise challenges for systems that base access control or other security considerations on linkages to 'subject'. E.g. if a List is associated with multiple Patient subjects, then it would be nominally part of multiple patient compartments, which might drive access rights.
