Use case: Including a contextual icon whose height is synced with text  
size and that degrades into nothingness.

Details:
  * The icon depends on the adjacent text content. It isn't mere style  
from a template made by a designer ahead of time. It is something the  
author of the text pastes in with the a text article. (This is here to  
counter "it's presentational; use CSS" solutions. :-)
  * The icon must be pasteable from the source of a stand-alone SVG  
icon.
  * When SVG in text/html is supported, the height of the icon must be  
specifiable in ems. The width must come from the aspect ratio of the  
viewBox.
  * When SVG in text/html is not supported, the icon must degrade into  
nothingness.
    - There must not be a blank CSS box of the size of the icon.
    - If the icon contains SVG text, this text must not be visible  
when the SVG rendering is not there.
