# Interface DOMImplementationList

    public interface DOMImplementationList

The `DOMImplementationList` interface provides the abstraction of an ordered collection of DOM implementations, without defining or constraining how this collection is implemented. The items in the `DOMImplementationList` are accessible via an integral index, starting from 0.
