The following is a note from the OGC Open Location Services Specification.
This specification was developed by a group of GIS and non-GIS companies and location
service providers from around the globe. It is starting to be used by Sprint,
vodaphone, H3G, and other providers. Because, many times they are dealing with
something as simple as a PDA or cell phone they have agreed to use WGS 84.
If it is determined that we need to handle alternative CRSs they should
be handled as an exception rather than the default.
We should not invent yet another new way of handling these.
Attached are examples of a Simple Feature GML line feature (trail),
point feature (utility), and polygon feature (inland water/lake). These are
complete features with attributes, bounding envelop, etc. I think we would only
be interested in the geometry making things much simpler.
The point is - note that the geometry Spatial Reference System (srs) is
identified by the registry name (EPSG) and the item in the registry (the
specific CRS – 4326)
