Note that servers may pre-cache summarized resources for optimal performance, so servers might not support per-profile use of the isSummary flag. When a request is made with _summary=true, serailisers only include elements marked as 'isSummary = true'. Other than Attachment.data, all data type properties are included in the summary form. In resource and data type definitions, if an element is at the root or has a parent that is 'mustSupport' and the minimum cardinality is 1 or the element is a modifier, it must be marked as isSummary=true.",
