Before leaving the subject of XML it is worth recording that XML is considered as the best approach for the future by many after it became a part of the standard for SQL from 2000. SQL is the most popular way to access and maintain data, so extending it from only working with relational (table based) databases, to updating XML formatted information has given XML a big boost ''(for example the WMO and ICAO have specified a XML and geographical location based approach for reporting weather conditions at airports and for some years have been persuading those running airports to swap from reporting METAR in traditional alphanumeric characters. ThoseThe werealphanumerical shorthand approach was introduced when the shortness of the code was critical for easy transmission by telex)''. The new approach is not designed for human observers and pilots to read the weather reports as reported, but being machine readable makes it easier for computer driven flying to take account of changing weather conditions and it can be presented to pilots in a more friendly graphical way, in the cockpit, changing the mix of information shown as they move along their route.
