For the option b, I would tend to not support you. I just recheck the 23.032 (Universal GeoGraphical Area Description), and the number of ways to express a position with velocity and uncertainty may not make the API simple.
Just have a look for instance the +CMOLR's XML DTD location_parameters. :)
Moreover, GPS vendors and other positioning professionals would find more logical to propose to use the WGS 84 datum for instance which is widely used and leave the burden to map the position to 3GPP style...
