I collected some ideas and problems about what authors can do and viewers 
can do to get some useful text alternative from an SVG - maybe this helps as
well for SVG fragments within (X)HTML:


It contains approaches using XHTML within SVG (following SVG 1.1) as well to
improve the semantics of text alternatives.
Obviously the alternative text presentation of viewers or readers have to
manage this as well to enable authors really to add some basic semantics
to text alternatives.
In SVG tiny 1.2 on the other hand this is excluded for title and desc, 
therefore authors have to add it into metadata, maybe using RDFa
or RDF (what is an option for SVG 1.1 as well).

I think, there are good options to generate text alternatives, but this
requires serious efforts both from implementors and authors, wanting to
provide text alternatives for SVG documents representing really some
relevant meaning, idea or content and nur just decorative funny color
