>             Project: Spatial Information Systems
>          Issue Type: Improvement
>          Components: Referencing
>    Affects Versions: 0.7

> The {{CRS.forCode(String)}} method accepts URL in the {{crs}} space, like 
> below:
> {noformat}
> http://www.opengis.net/def/crs/epsg/0/4326
> {noformat}
> We need to also accept URL in the {{crs-compound}} space, like below:
> {noformat}
> http://www.opengis.net/def/crs-compound?
> 1=http://http://www.opengis.net/def/crs/OGC/0/AnsiDate&
> 2=http://www.codes.wmo.int/GRIB2/table4.5/IsobaricSurface
> {noformat}
> It should be possible to use this kind of CRS in GML like below (example from 
> U.K. MetOffice):
> {code:xml}
> <cis:envelope srsName="http://www.opengis.net/def/crs-compound?
>                        
> 1=http://http://www.opengis.net/def/crs/OGC/0/AnsiDate&amp;
>                        
> 2=http://www.codes.wmo.int/GRIB2/table4.5/IsobaricSurface";
>               axisLabels="Time pressure" srsDimension="2">
>     <cis:axisExtent axisLabel="Time" uomLabel="ISO8601" lowerBound="PT0H" 
> upperBound="PT48H" />
>     <cis:axisExtent axisLabel="pressure" uomLabel="hPa" lowerBound="1000.0" 
> upperBound="200.00" />
> </cis:envelope>
> {code}
> If using the URN syntax, then this is rather a comma-separated value list 
> (more description in [Definition identifier URNs in OGC 
> namespace|http://portal.opengeospatial.org/files/?artifact_id=24045]). 
> Example:
> {code}
> urn:ogc:def:crs,crs:EPSG:6.3:27700,crs:EPSG:6.3:5701
> {code}
