  7. CWA3-2 XBRL handbook for declarers • The extensibility of XBRL • XBRL is extensible by design. The original authors of XBRL were aware of the complexity and diversity of reporting all over the world. As result, XBRL was designed to be a flexible language in order to suit as many use-cases as possible. In addition to the extensible nature of the language itself, taxonomies (schemas) can be extended with additional concepts and new relationships.

  8. CWA3-2 XBRL handbook for declarers • XBRL Dimensions • Multidimensional data models are known for their use in the analysis of business information. • The basic elements of this model are: metrics, dimensions, domains and hypercubes. • Metrics represent primary business concepts (line items, or ‘primary items’). • Dimensions represent ways to break down the data, or to express characteristics (for example: “before mitigation” or “after mitigation”). Examples of dimensions include: Time, product line, clients, geography. • The set of possible values within a dimension is called a domain.
