Find
sources such as ESRI data and convert. ESRI also has a
proprietary XML language for its data, and there is GML (Geometry
Markup
Language). The trick is, as you know, not the geometry
data
types, but the layers for feature types (eg, roadways, railways,
etc.).
ESRI
is proprietary but a de facto standard for geospatial mapping.
The
whole domain of location-based services is quite hot. SVG
products are part of that. You'll find that industries
working with
utilities, public safety, etc. are already all over this
one.

>>5. Suppose that I want to create an SVG image of a
country. I cannot imagine handcrafting an XML SVG document. How do
you suggest that I create the SVG document?<<
There are a number
of tools that work from images to generate path statements for SVG. Adobe
Illustrator is a good example-- anything done there can be saved to SVG.
Additionally, there are some great pure SVG tools out there such as XStudio
(http://www.evolgrafix.com). I believe
there are some opensource converters out there, but don't know them off
hand.
