ANSI CTA-2018-2008 pdf download Task Model Description (CE TASK 1.0)
2.1 Task Model Description Conformance of task model descriptions is relevant to authors of task model descriptions, because it allows a task model description to be used by any task-based application based on this standard. An XML document is a valid task model description if it conforms to the requirements outlined in 7 through 1 0 of this standard. The syntactic validity of task model descriptions is completely and unambiguously established by the RelaxNG schemas in this standard, including the comments added to express restrictions that are not expressible in the schema language. (See Annex A for complete schemas.) The semantics of task model descriptions is established by describing in words how a given document specifies a task model. A task model is an abstract mathematical construct, which is defined in this standard using common notions such as class, instance, set, function, etc.
2.2 Task-Based Application Conformance of task-based applications is relevant to implementers of task-based applications, because that want their applications to make proper use of conformant task model descriptions. The behavioral connection between a task-based application and the task model description it uses is established indirectly via the recommendations in 1 1 . These are only recommendations, rather than mandatory requirements, because of the great variation possible in task-based applications. For example, this standard does not prevent an application from ignoring some aspect of the task model under direct instructions from the user.
2.3 Grounding Conformance of the ECMAScript programs used for grounding is relevant for implementers of network platforms and devices, because it allows their platforms and devices to be used by taskbased applications. The ECMAScript programs conform to this standard if they obey the specifications in 1 0.
