Add a 'cursor' like feature in SSML tag
Allow the drill-down feature inside the <speak> tag to track the currently spoken groups of words.
Example use case: reading news headlines with the ability to read the whole article.
<meta id="1">News headline 1. Brief content...</meta>
<meta id="2">News headline 2. Brief content...</meta>
Alexa should keep track on the current id. When a user requested to read the whole article, the intentHandler will be able to fetch this id from the handlerInput.requestEnvelope or whatever scope and use this id to fetch the article.
The developer should map this id with the reference to the actual http address or other resource during the speechOutput creation.
