</div><div><span class="Apple-style-span" style="font-family: Helvetica; line-height: 19px;"><br class="webkit-block-placeholder"></span></div><div>There is two cases: when the browser supports the XML dialect natively or it doesn&#39;t. When the browser does then browser EH plug-in is the browser itself (another words: browser EH plug-in is hardcoded into browser). For example, like we have in Firefox for HTML. There we expose HTML content to AT by AT API (like ATK or IAccessible2) usage. If the browser doesn&#39;t support some XML dialect then browser EH plug-in may be a JS script that allows the browser to expose that XML content to AT and here @implements attribute is used to define when that script should be executed. In this chain I don&#39;t get what role does AT EH plug-in play. Is it used when the specialized markup should be transformed to information to be used by something else than screen readers? Where are&nbsp;ontologies&nbsp;here?</div>
