description: This extension is for use when a value set is to be used to render a list of code choices for human selection (typically in Questionnaires). It allows specifying a prefix to put in front of the display name of the code display value. For example \"a)\", or \"iii.\" or \"1]\". This only works if the value set is defined extensionally (i.e. enumerating the codes). If defining an intensional value set with the definition \"all codes from code system [some code system]\", then use the [codesystem-label](StructureDefinition-codesystem-label.html) extension instead.\n\nPrefixes are particularly relevant if there are textual instructions that accompany the question. E.g. 'Do not select more than one of options a, b, or c' on a multi-select question.
