Enhanced Page

An enhance page is a self contained HTML DOM Document with a resolver. In scripts you can access it using Resolver("document"). The enhanced features of the document are maintained under essential. You will normally not need to access these.

The page can be configured using tags in the HTML.

Tag	Use
<meta name="lang cookie" ..>
<meta name="text selection" ..>
<meta name="enhanced roles" ..>
<link rel="subresource" ..>
<script type="application/config">
<script type="application/init">
<.. role=.. data-role=..>

Is a document enhanced? test document.essential not undefined.

API on document.essential

As functionality matures it is move to Generator, Resolver and the HTML markup. Expect major releases to obsolete some of the API as the functionality is directly available.

Other pieces are shims to make older browsers work better E.G. MutableEvent.
