[postgis-users] spatial_ref_sys

I'm working in Alberta which uses a modified Transverse Mercator
projection (called 10TM) for provincial scale data.

AFAIK there is no entry in spatial_ref_sys to describe this projection.
Is there some protocol by which an entry might be added to future
versions of PostGIS and is there a recommended procedure for numbering
my own entry to avoid conflicts with future versions?

If I add my own following the format provided, I an import my data with
the -s flag and it displays nicely in QGIS, which I assume indicates
that it is functional and coordinate conversion, and other functions
will operate properly. Right?

Thanks in advance.
