Hi Carmen:
Nobody has gotten back to you; in part because the 52N developers do not play
an active part in the GeoTools project; and in part because I am not exactly
sure what version of GeoTools they are using.
You are welcome to go through the code with respect to encoding elements
(thanks for the notes on EPSG:4936 etc… it is a very complete description).
You may also consider making a bug report with a test case and placing it into
Jira; it really helps the developers reproduce the problem.
Finally if you are a 52N customer perhaps they can persue this issue in greater
detail for you?
As an aside I am keen to hear about the WPS you are working on :-)
