2.2.7.2 Supporting Link

Each formula element (section 2.2.2.6) which references external data refers to an Xti (section 2.5.173). The Xti specifies a particular supporting link record (section 2.2.7.3) from the collection stored in the workbook. The Xti and supporting link record together specify where the data used by the formula element resides, and in certain cases, additional data about the supporting link.
