These are the change notes for release 2.0 of TransXChange

    It shares common NaPT data types with the NaPTAN 2.0 release which is released simultaneously 

    It has been tested against Java and MS validators.

    It is accompanied by a set of  example documents available at www.transxchange.org.uk.
        - The examples are intended to demonstrate the use of all the main TXC features and every possible route topology.
          An index page shows which features are used one each example.
        - Each example is explained by a web page with timetable and route maps.
        - Some further examples covering partial exchange of data are planned.
    
    A revised version of the Schema Guide is available with minor revisions.
