Start with the PVS-Studio findings in the named files, including mayadmdagnode.h, mayadmtypes.h, generatedsaxparsertypes.h, colladamayadocumentexporter.cpp, and colladabuuri.cpp. Run the PVS-Studio check and inspect each reported warning; done means the listed warnings are addressed without introducing new analyzer findings.
