 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.

See also the Document Object Model (DOM) Level 3 Core Specification.

Since:1.5, DOM Level 3
