HDML
Handheld Device Markup Language
Handheld Device Markup Language is a modified form of HTML (Hypertext Markup Language), and is deigned for use of wireless devices, or small computers such as PDA (Personal Digital Assistants). Like WML (Wireless Markup Language), HDML is formatted on cards which are smaller units of information than traditional HTML which uses pages. This small data unit is more suitable for viewing on handheld devices and is quicker to download onto wireless devices.
