/** This attribute complements the default
 * {@link com.github.czyzby.lml.parser.impl.attribute.building.StyleLmlAttribute}. However, this is not just an alias:
 * style attribute is parsed BEFORE the widget is created, so if you pass an action reference in style attribute, the
 * invoked action will receive no argument. Frames attribute is parsed DURING actor creation, after its instance already
 * exists, so it can properly handle method references.
 *
 * <p>
 * This attribute expects an LML array of drawables stored in the default skin. Note that this attribute will NOT
 * override frames passed in the style attribute: it will append new frames to the existing frames array, making it
 * possible to use frames from two separate skins (if needed). Mapped to "frames".
