56 * Platform creation functions. Instead of passing 123 arguments to the creation functions
57 * (one for each possible XML attribute), we pass structures containing them all. It removes the
58 * chances of switching arguments by error, and reduce the burden when we add a new attribute:
59 * old models can just continue to ignore it without having to update their headers.
61 * It shouldn't be too costly at runtime, provided that structures living on the stack are
62 * used, instead of malloced structures.
