The Calculation Chain part consists of an application-specific cache of information.

Content type: application/vnd.ms-excel.calcChain

Source relationship: http://schemas.openxmlformats.org/officeDocument/2006/relationships/calcChain

This cache exists for performance reasons only, and can be rebuilt based on information stored elsewhere in the file without affecting calculation results. A package SHOULD NOT<1> contain this part.

A package MUST contain no more than one Calculation Chain part. If it exists, that part MUST be the target of an implicit relationship from the workbook (section 2.1.7.61) part.

A Calculation Chain part MUST NOT have implicit or explicit relationships to any part.
