Field Card. Type and Description 
contains 0..*List<Contains>The codes that are contained in the value set expansion.id 0..1Stringunique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.identifier 1..1UriAn identifier that uniquely identifies this expansion of the valueset. Systems may re-use the same identifier as long as the expansion and the definition remain the same, but are not required to do so.offset 0..1IntegerIf paging is being used, the offset at which this resource starts. I.e. this resource is a partial view into the expansion. If paging is not being used, this element SHALL not be present.parameter 0..*List<Parameter>A parameter that controlled the expansion process. These parameters may be used by users of expanded value sets to check whether the expansion is suitable for a particular purpose, or to pick the correct expansion.timestamp 1..1DateTimeThe time at which the expansion was produced by the expanding system.total 0..1IntegerThe total number of concepts in the expansion. If the number of concept nodes in this resource is less than the stated number, then the server can return more using the offset parameter.Key: = Must support, = QICore-defined extension, = Is-Modifier
