The SVG itself sets its size in em. It inherits that value from the browser
default, as set by the user.

example:

HTML page source:

... <img src="some.svg" alt="a cool browser makes this appear as text"/> ...

SVG source:

<svg width="17em" height="12em" viewbox="...

...<style><[CDATA
   .fancytext {font-size:1.7em}...


CSS user stylesheet (which the browser created for the user with a nice
interface...)

html, svg {font-size: 36pt !inherit}

(since they don't have constraint-based CSS except in a development demo of
Amaya - sigh)

Alternatively, it makes sense to use foreignObject to include old fashioned
HTML content in SVG quite often, which would of course inherit HTML styles
from the browser. (The adobe plugin doesn't yet. Amaya does. Batik is a
standalone, but allows a user style sheet. The SVG group knows more...)

  I don't understand. If there's no size at all, what's to inherit?
