geolocation	Geolocation : The absolute geographic location of the Location, expressed using the WGS84 datum (This is the same co-ordinate system used in KML).
translation	Translation : Language translation from base language of resource to another language.
tz-code	Timezone Code : An IANA timezone code for the timezone offset per BCP 175. The offset is specified as part of a dateTime/instant (or using the tzOffset extension on a date if necessary). The timezone code may also be provided to allow for human display of the location associated with the offset.
tz-offset	Timezone Offset : Timezone offset, for dates where timezone is not allowed as part of the base date.

originalText	Original Text : A human language representation of the concept (resource/element) as seen/selected/uttered by the user who entered the data and/or which represents the full intended meaning of the user. This can be provided either directly as text, or as a url that is a reference to a portion of the narrative of a resource (DomainResource.text).
