Wireless Markup Language

It provides navigational support, data input, hyperlinks, text and image presentation, and forms, much like HTML (Hypertext Markup Language).

It preceded the use of other markup languages used with WAP, such as XHTML and HTML itself, which achieved dominance as processing power in mobile devices increased.

The Telfort WML site was created and developed as side project to test the device's capabilities by a billing engineer called Christopher Bee and National Deployment Manager, Euan McLeod.

WML decks are stored on an ordinary web server configured to serve the text/vnd.wap.wml MIME type in addition to plain HTML and variants.

The gateways send the WML pages on in a form suitable for mobile device reception (WAP Binary XML).
