Easy math input language; Unicode extension

1. Extended-MML?

Is it still the ambition of the HTML-Math WG to define 
such a language for easy math input (and possibly fall-back
representation of math for web browsers lacking special
math support) as a layer above the basic MathML layer?

2. Extension of Unicode

The charter of the HTML-Math WG [2] contains this passage:

> It will be desirable to request from Unicode the registration of
> a large number of characters used in mathematics but as yet with
> no place in Unicode. 

Has such a request been made? If so, is it publicly available?
