Calculations 1.1

Calculations 1.1 provides minor improvements to the "summation-item" mechanism defined in the XBRL v2.1 specification. The specification provides improved handling of rounded and duplicate facts, which are particularly relevant to Inline XBRL-based reporting.

The specification also updates the definition of calculation functionality to leverage semantic definitions provided by the Open Information Model, rather than the XML syntactic definitions of XBRL v2.1.
