What is the difference between the TransXChange Registration and the General schema ?
There are two slightly different versions of the TXC schema: a registration schema, used for submitting Electronic Bus Service Registrations (EBSR) to VOSA, and a general schema that can be used for general purpose exchange of all or part of a timetable. The two variants are almost identical, except that in the EBSR registration version certain fields are mandatory. The general schema in contrast allows TXC to be used to exchange arbitrary subsets of TXC elements, without all the mandatory details required by the registration schema. A TXC document that conforms to the registration schema will always also conform to the general schema. A document that conforms to the general schema may conform to the registration schema, but is not guaranteed to do so – it may be lacking some mandatory elements in which case it will not. Documents that conform to either schema may be published with the TXC publisher.
