0. Extension

A release label assigned for the version.
Optional Extension Element - found in all resources.

Release labelOptional Extensions Element
Comments
To provide a human-friendly label for an artifact version that might convey meaning beyond the version (e.g., "2023Q2" might be a useful label for indicating that a release artifact is relevant for or was released in the 2nd quarter of 2023).
ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists())
2. Extension.url
Definition
Source of the definition for the extension code - a logical name or a URL.
Short
identifies the meaning of the extension
Comments
The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension.

2. Extension.id
Definition
Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
May be used to represent additional information that is not part of the basic definition of the element. 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 can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
Short
Additional content defined by implementations
Comments
There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
