## Attributes

`engine`

- The full version of the ®ina; calculation engine that wrote this data file.

  If a newer version of ®ina; exports to an older ®ina; file format, then the `engine` attribute will reflect the newer version of ®ina; that actually wrote the file.

  If this file was created by hand or by an external program, the `engine` attribute should reflect this (it might contain the name and version of the external program, for instance).
