Create wiki documentation for IS:etcsArea
The ETCS working group has created a draft documentation that can be used to create a wiki documentation for the railML 3 element etcsArea. The existing work includes a definition as well as example information.
This ticket is to create the wiki page from that documentation provided by the ETCS community.
