Re: Draft talk Maps for the Web Workshop

Hi Nicolò,

I'm just back from holidays myself and want to bounce some thoughts 
relating to your suggestion below.

I'm wondering how we can tie this into a general thread around the need 
for improved semantics? Or do you feel it is sufficient to demonstrate 
what can be currently done with ARIA/HTML and other meta data?

Some other thoughts:

  * Should we explicitly frame the talk proposal in the context of
    current semantic limitations from an a11y perspective? I'm not
    saying we should btw, and am genuinely asking the question.
  * Will your presentation demo the use of particular polyfills? Or the
    need to support some kind of brittle plug in architecture to build
    accessible map implementations?
  * Are there other current APA specs or works in progress, such as
    Personalisation or Pronunciation that we could demonstrate here also?

Apologies if that sounds like too much ground to cover (likely is) but 
these thoughts came to me when reviewing this.
