This is a non-issue.  The *overwhelming* majority of blind Web users use
mainstream browsers (Lynx is a mainstream browser), not "really dumb"
tools.  BTW, a "screen reader" is a program that takes data from the *user
interface presentation* and routes it to speech or Braille output; it's
completely unaware of the internal representation that an application
program uses to create its display.  Misguided attempts at accessibility
are patronizing as well as wasteful.  Accessibility of SVG documents to
blind users will come either from accessible interfaces provided by
"mainstream" SVG display tools (in which case the internal representation
is completely irrelevant) or from specialized SVG-interpreting tools
(which can be assumed to fully parse the SVG and probably build a DOM out
of it; there's no reason to make SVG hack-parse friendly on their

Is this requirement really "an SVG document should display its textual
content if loaded into a browser that supports only HTML"?
