Great

Even better. But as you notice that immediately brings up:

Which is addressed here

http://www.w3.org/TR/SVG11/coords.html#GeographicCoordinates

which in turn references

http://www.opengis.org/techno/specs/01-014r3.pdf

Basically, the Coordinate Reference Systems and Coordinate
Transformations are describes using an industry standard vocabulary
from the Open GID Consortium, and the whole thing is put in a metadata
element. This can be short, if referring to well-known coordinate
systems, or verbose if describing custom ones.

The SVG WG would be particularly glad of further review of this
section from people whose interests include GIS, location based
services, geology, archaeology, historical mapping, etc etc.
