+<h3 id=domstringlist>The {{DOMStringList}} interface</h3>
+<!-- ============================================================ -->
+
+The {{DOMStringList}} interface represents an immutable ordered
+collection of zero or more {{DOMString}} values. The items in a
+{{DOMStringList}} are accessible via an integral index, starting from
+zero.
+
+<aside class=note>
+  The {{DOMStringList}} interface was previously defined in
+  [[DOM-Level-3-core]] but has been removed from the current versions
+  of [[DOM]] and is now only referenced in this specification. It is
+  hoped that in the future all uses of this type can be replaced by
+  conceptually similar <code>FrozenArray&lt;DOMString&gt;</code> to
+  enable the use of other [=Array=] methods, but retaining support for
+  the {{DOMStringList/contains()}} method for compatibility with
+  deployed content.
+</aside>
+
+<pre class=idl>
+interface DOMStringList {
+    readonly attribute unsigned long length;
+    getter DOMString (unsigned long index);
+    DOMString? item(unsigned long index);
+
+    boolean contains(DOMString str);
+};
+</pre>
+
+The [=supported property indices=] for a {{DOMStringList}} |list|
+are the numbers zero to the number of items in |list| minus one.
+If |list| has no items, it has no [=supported property indices=].
+
+To [=determine the value of an indexed property=] for a given index
+|index| in a {{DOMStringList}} |list|, return the |index|<sup>th</sup>
+item in |list|.
+
+The <dfn attribute for=DOMStringList>length</dfn> attribute's
+getter must return the number of items in the collection.
+
+The <dfn method for=DOMStringList>item(|index|)</dfn> method must
+return the |index|<sup>th</sup> item in the collection, or null
+if there are less than |index| + 1 items in the collection.
+
+The <dfn method for=DOMStringList>contains(|str|)</dfn> method must
+return true if |str| is equal to any item in the collection, and false
+otherwise.
