XBRL instance documents contain financial data and disclosures for a specific entity, reporting period, and currency. The document describes the key components of an XBRL instance document, including the root element, schema and taxonomy references, contexts, units, and items that contain the reported values defined in the taxonomy. Relationships between elements are defined using linkbases for presentation, calculation, dimensions, labels, and references.
