Manuel,
Would you mind submitting the patch via bugzilla? I generally hate to add new
projection forms to OGR (thereby setting a WKT representation in stone) till
I have also reviewed ESRI and other WKT sources to see if they already have
a format for that projection. Handling it through bugzilla will give me the
time to review and look at other sources before doing anything.
I would add that the interrupted form is what I really want to (as far as
I understand it).
Best regards,
--
