| SubscriptionTopic.id | 0..1 | http://hl7.org/fhirpath/System.String | The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes. |

| SubscriptionTopic.implicitRules | 0..1 | uri | A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc. |
| SubscriptionTopic.language | 0..1 | code | The base language in which the resource is written. |
| SubscriptionTopic.text | 0..1 | Narrative | A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human.

Resource definitions may define what content should be represented in the narrative to ensure clinical safety. |
| SubscriptionTopic.contained | 0..* | Resource | These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope. |
