<p><code>List of <i>features</i>. Default is the empty list.</code></p>

<p>A feature is string tag that can be enabled or disabled on a target. The
  meaning of a feature depends on the rule itself.</p>

<p>This <code>features</code> attribute is combined with the <a href="${link
package}">package</a> level <code>features</code> attribute. For example, if
the features ["a", "b"] are enabled on the package level, and a rule
<code>features</code> attribute contains ["-a", "c"], the features enabled for the
rule will be "b" and "c".
