     * 
     * The *speakable* property can be repeated an arbitrary number of times,
     * with three kinds of possible 'content-locator' values:
     * 
     * 1.) *id-value* URL references - uses *id-value* of an element in the page
     * being annotated. The simplest use of *speakable* has (potentially
     * relative) URL values, referencing identified sections of the document
     * concerned.
     * 
     * 2.) CSS Selectors - addresses content in the annotated page, eg. via
     * class attribute. Use the [[cssSelector]] property.
     * 
     * 3.)  XPaths - addresses content via XPaths (assuming an XML view of the
     * content). Use the [[xpath]] property.

     * references, either CSS selectors or XPath expressions to pick out
     * document section(s) as speakable. For this
