error compiling classes when using a schema with a redefined subelement

when trying to compile the two schemas ('Core.20020831.xsd' and 'Core.20020225.xsd') i get a java compile error because of an overridden 'getInfo()' method in 'ReferencesCheckResultType', which declares a different return type in the base type 'CheckResultType'. you have to compile the schema using the -nopvr option.

the root cause is: while 'ReferencesCheckResultType' is derived from 'CheckResultType', it also declares an 'Info' subelement which has a different type than the 'Info' subelement in 'CheckResultType'. although from a xml schema point of view these two types are compatible.

i didn't find any way to work around this. i think this is a rather fundamental problem, rooted in the mismatch between the xml schema model and java object model. maybe there's a way of working around this by configuration (e.g. by being able to redefine the names of getters/setters for certain subelements).
