It's not too complex, there is already some code in osgDB that
verifies floats fields as part of .osg parsing. This code could
probably be adapted. It's just another tasks on that requires some
time, and I'm rather overstretched. Others are welcome to dive in a
code a solution.

If we don't control the output and input to be just be '.' then we'd
need to store the local along with the .osg file itself. I'd be
inclined to standardise on . as the decimal place as this is the
standard throughout most of the world.

We might have to look at writing and well as read. Setting the local
would need to be done before any write to .osg or read from .osg.
