FEATURES ( Collection of FEATUREs )

Defines the feature space for the model. The FEATURES node declares all input features that may be referenced by rules, expressions, and runtime evaluation logic. Features defined here establish the vocabulary used for inference, but do not assign values until input is provided.

Range	RANGENODE	Defines the valid range of values for this feature.
Interval	DECIMAL	Specifies the interval or step size used when evaluating numeric values.
