List of feature strings; optional
A feature is string tag that can be enabled or disabled on a target. The meaning of a feature depends on the rule itself.
This features
attribute is combined with the package level features
attribute. For example, if
the features ["a", "b"] are enabled on the package level, and a target's
features
attribute contains ["-a", "c"], the features enabled for the
rule will be "b" and "c".
See example.
