SubstanceInstance A homogeneous material with a definite composition.
id Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
extension_
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.
modifierExtension
May be used to represent additional information that
is not part of the basic definition of the element and that modifies the
understanding of the element in which it is contained 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 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. 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).
identifier
Identifier associated with the package/container (usually a
label affixed directly).
expiry
When the substance is no longer valid to use. For some
substances, a single arbitrary date is used for expiry.
expiryElement
Extensions for expiry
quantity
The amount of the substance.
