If not focus is specified, the focus is assumed to be focus of the parent section, or, for a section in the Composition itself, the subject of the composition. Sections with a focus SHALL only include resources where the logical subject (patient, subject, focus, etc.) matches the section focus, or the resources have no logical subject (few resources).","Typically, sections in a doument are about the subject of the document, whether that is a  patient, or group of patients, location, or device, or whatever. For some kind of documents, some sections actually contain data about related entities. Typical examples are  a section in a newborn discharge summary concerning the mother, or family history documents, with a section about each family member, though there are many other examples.","","","","","","","","",,,,,"",,,,"Composition.section.focus",0,1,"","ele-1:All FHIR elements must have a @value or children {hasValue() or (children().count() > id.count())}
