Some quotes from the WML specification: 1) The 'name' attribute: "This attribute specifies the property name. The user agent must ignore any meta-data named with this attribute. Network servers should not emit WML content containing meta-data named with this attribute." 2) The 'forua' attribute: "If the value is "false" an intermediate agent MUST remove the "meta" element before the document is sent to the client. If the value is "true" the meta data of the element MUST be delivered to the user-agent. The method of delivery may vary. For example, http-equiv meta-data may be delivered using HTTP or WSP headers." 3) The 'scheme' attribute: "This attribute specifies a form or structure that may be used to interpret the property value. Scheme values vary depending on the type of meta-data." Test & implement these attributes.
WML support is removed - http://trac.webkit.org/changeset/85256.
