assimp calls all importers in the order in which they
are registered and each importer gets the opportunity
to load the file until one importer "claims" the file. Apart
from file extension checks, importers typically use
other methods to quickly reject files (i.e. magic
words) so this does not mean that common or generic
file extensions such as XML would be tediously slow. */
