What is an XBRL instance document?
An XBRL instance document is an XML data structure, meeting the XBRL specification and reporting a set of facts. At a more basic level, an XBRL instance document contains the actual facts of a business report, where each fact is marked up in a manner that associated it with a given XBRL taxonomy concept. The markup for each fact also references a variety of contextual information that indicate how each fact is to be interpreted. The context describes the key features of the fact (who reported it, the period to which the information pertains, etc.).
