The Environment Agency (EA) has its own bespoke XML-based schema for its FWD, FWIS and Floodline systems. The FWD standard follows the usual XML format consisting of a declaration, a root element and child/sub-elements. It differs from the CAP standard in the terminology used (being more specific to the FWD and FWIS systems) but uses the same Base64 encoding for embedded resources. The EA acknowledges the ease at which the EAFWD schema can be converted to a particular style of CAP XML but highlights how CAP XML is not specfic enough to improve interoperability over existing systems. The possibility of extending the EAFWD schema to fit a more generic national alert system could be worth investigating as FWD already generates content for mobile SMS messages.
