Description (last modified by )
While opening the attached shapefile we can see this:
JOSM was unable to find a strict mathematical transformation between 'GCS_SIRGAS_2000' and WGS84.
But from http://www.ibge.gov.br/english/geociencias/geodesia/pmrg/faq.shtm#15 we have:
15. Are there transformation parameters between WGS84 and SIRGAS2000? There are not such parameters between SIRGAS2000 and WGS84 because they are practically equal, that is, DX = 0, DY = 0 and DZ = 0.
So opendata could support SIRGAS2000 without doing anything special (and without giving any kind of warning).
Also, at the same page we have two more coordinate transformations that could be useful for opendata:
Since the establishment of GPS(Global Positioning System), its Geodetic Reference System (WGS84) has been updated three times. The purpose was to align it to ITRFyy, the most accurate ITRS realization. The latest update was named WGS84 (G1150), adopted in the GPS system since January 20th of 2002. The SAD69 / WGS84 transformation parameters, published in the Resolution of the Presidency of IBGE number 23, of 21/02/89 (R.PR 23/89), are valid to transform the coordinates between SAD69 / WGS84 in GPS observations conducted in the period from 01/01/1987 to 01/01/1994. WGS84 to SAD69: DX = +66.87 m DY = -4.37 m DZ = +38.52 m The SAD69 / SIRGAS2000 parameters, used in TCGeo and ProGriD (option: SAD69 Doppler Technique or GPS) and published in the Resolution of the Presidency of IBGE number 1, of 25/02/2005 (R.PR 01/05), are valid to transform the coordinates between SAD69 / WGS84 and SAD69 / SIRGAS2000 in GPS observations conducted after 1994. SIRGAS2000(WGS84 (G1150)) to SAD69: DX = +67.35 m DY = -3.88 m DZ = +38.22 m

Fixed in [o33356:33357].
I have not added the information concerning your projections only bur rather included the whole ESRI database (more than 7000 projections) obtained from Github (Apache 2.0), so this is a huge enhancement :)
I have created a feature request to GeoTools for a related message: https://jira.codehaus.org/browse/GEOT-5062
