Arelle, Solvency II Edition, is based on  Arelle , an open source project. It is a standalone application that supports the edition, the display and the validation processes of Solvency II reports. 

Arelle is largely used by XBRL experts, software editors and national supervisors. This large spectrum of users guarantees compliance with the XBRL standard

The solution is taxonomy-agnostic: it implements Solvency II reporting of the EIOPA as well as  the CRD IV of the EBA or the National Specific Templates (NST) of the Central Bank of Ireland (CBI)

Acsone improvements consist of increasing the usability and the functional coverage of Arelle for Solvency II production; the support for QRT Excel files and the displaying of cells in error are such improvements. 

No license fee, but a yearly subscription that ensures the required maintenance and support.
