CMN Welcome to the group! Yes, it is possible and there is work on the topic.
See below.

  I guess for just now it would require that page creators enter some Meta
  information although I see no reason why this can't be part of tools as
  it is the next "thing" of graphics anyway. Vector graphics using XLM has
  had much work done on it and this could be extended to support
  accessibility (and maybe already hs???).

(I am assuming XLM is a typo for XML) Yes, there is work on graphics in XML,
a language called Scalable Vector Graphics (SVG) is a W3C Proposed
Recommendation, and a year ago W3C published a Note called "Accessibility
Features of SVG" at http://www.w3.org/TR/SVG-access (I co-wrote it with
Marja-Riitta Koivunen)  which explored some of these topics. More recently
Guillaume Lovet wrote a text-only SVG browser as a summer project to make use
of this, and Ivan Herman of W3C collected some further observations on the
topic. There is a discussion thread on this work in the public xtech mailing
list - wai-xtech@w3.org - starting at
http://lists.w3.org/Archives/Public/wai-xtech/2001Jul/0000

Cheers
