Hello,

it could be useful to have a declarative method in SVG to
orient a map relative to the current orientation of the
device (including text rotation) - some people have
problems with maps with a different orientation then
themselves and reading text upside-down.
And with the upcoming 3d transforms it can be
interesting to orient and align a simple 3d-scene
relative to the current position and orientation of
the device.

Another interesting related issue is a tool to help
the audience to orient the device in a specific 
direction. But this is maybe too complex for a
declarative method and may require scripting.
However this can help to find locations or
directions to stars including maps realised with SVG.

Other obvious applications are changes of svg element
attributes like width, height, viewBox, preserveAspectRatio
due to the orientation of the device and the size of the
current viewport.

Similar to the map case above it could be an application
to rotate only descriptive text (and logos, icons etc) and 
maybe a future tooltip-element  representation automatically 
in an SVG to simplify reading, if the device is turned around.
