XBRL element is linked. BACKGROUND ON XBRL
XBRL is a standardized way to electronically identify business data. As such, XBRL
facilitates electronic data processing and communication.
XBRL is used throughout the world for a variety of internal and external business
reporting purposes. Several national securities regulators require or encourage publicly held
companies to publish financial statements in XBRL format instead of, or in addition to, other

financial statements as additional exhibits to annual reports (10-Ks), quarterly reports
(10-Qs), registration statements, and other filings. Lesson 16: Working with XBRL Elements 157 Basic Concepts

the element CashAndCashEquivalentsAtCarryingValue could be used to tag a number that is
the ―Cash and Cash Equivalents‖ balance that an entity reports on its balance sheet.

characteristics, and interrelationships. An entity could use the elements in an XBRL
taxonomy, for example, to tag the various items of numeric and textual data that appear in the
entity’s financial statements.
An instance document is an electronic file containing a specific set of data that has

specific taxonomy and has generated the required XBRL files has created an XBRL instance
