  to the Union Flag are also national flags under the law. Similar situations may, 
  however, exist in other countries, and the applicable country's laws should be 
  consulted to determine the status of such flags (see also 
  union jack).
 b) In the sub-divisions 
  of some countries – such as the Länder of Germany or provinces of Spain – there 
  are variants of the relevant flags for civil and official use – see civil flag 
  and official flag 2) (also ceremonial flag 1)
