1. Extension
Definition	Breast Body Location Extension
Control	0..* This element is affected by the following invariants: ele-1
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.

XML Representation	In the XML format, this property is represented as an attribute.
3. Extension.extension
Definition	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 manageable, 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.
