Nexus EMR profile for an ATTACHED DOCUMENT -- a clinical document that exists as a file: scanned paper, incoming faxes, external consult letters received as PDF, signed consent forms, patient-uploaded files. FHIR holds the metadata and clinical context; the bytes live in document storage and are reached through content.attachment.url.

WSIB Form 8 Template (with field mapping)

The tenant-wide blank of WSIB Form 8 -- subject-less, marked under nexus-form-template, readonly because it is system-provisioned -- carrying the field mapping that pre-fills the patient's name, date of birth, sex, phone and address into the file's own field names when a form is started from it
