public class Attributes extends Object implements Iterable<Attribute>, Cloneable
Attributes are treated as a map: there can be only one value associated with an attribute key/name.
Attribute name and value comparisons are generally case sensitive. By default for HTML, attribute names are normalized to lower-case on parsing. That means you should use lower-case strings when referring to attributes by name.
