Exactly, in the Restlet API, we have a generic Parameter class (a name/value
couple) and then we define a Series<E extends Parameter> class which
implements List<E extends Parameter> interface and adds many helper methods
(like getFirstValue() and add(name, value).
The advantages are the ability to keep track of the initial order of the
headers, to handle repeating headers. Also it stikes a good balance between
memory usage and performance.
Best regards,

PS: The correct spelling is "Restlet" instead of "RESTlet" :)
