What makes it seem so?
This is not the case as far as I’m aware.

Are you thinking of the RSVG library? It’s not part of cairo. It’s also 
only a renderer and does not seem to be designed to do anything else.

You may want to look at CairoSVG (another renderer, in Python) and mess 
with it’s internal tree representation, but that’s little more than the 
XML tree.
