The EU Officially Recognizes XBRL as a Standard

The EU Multi-Stakeholder Platform (MSP), an expert group composed of EU member states, standards setting organizations and other stakeholders, has recommended XBRL as an Information and Communications Technology (ICT) Standard. The European Commission has in turn approved XBRL as eligible for referencing in public procurement, at the same level as other Standards such as W3C XML or those by the ISO. (Source)
