Handheld Device Markup Language (HDML)

Handheld Device Markup Language is used to format content for Web-enabled mobile phones. HDML allows Internet access from wireless devices and is derived from HTML. Openwave created this proprietary language, and it can only be viewed on mobile phones that use Openwave browsers.

HDML was created before a WAP standard was defined. It uses Openwave's Handheld Device Transport Protocol (HDTP) instead of WAP.
