Imports

The HTML Imports specification is the normative description of this part of Web Components.

Custom elements and decorators can be loaded from external files using the link tag:

<link rel="import" href="goodies.html">

Only <decorator> elements and <element> elements are interpreted by the user agent, although the DOM of this document is available to script through the import property. Documents which are retrieved cross-origin use CORs to determine that the definitions are designed to run cross-site.
