ZDoom Strife Dialog Format
From ZDoom Wiki
(development version r2561+ only)
The ZDoom Strife Dialog Format is a variant of the Universal Strife Dialog Format. It is not a proper USDF dialect since it changes the semantic of the actor field from an integer into a string corresponding to the actor class name, resulting in a type mismatch in a strict parser. This deviation from the standard was deemed necessary to avoid forcing modders to use the ConversationID property on all actors, which would require as well redefining any standard actor without this property.
