/**
 * Grammar for common elements of the UML/P-Language-Family
 *
 * The grammar contains the modifiers that UML provides.
 * This includes "public" "private", "protected", "final", "abstract", "local",
 * "derived", "readonly", and "static", but also the
 * compact syntactic versions "+", "#", "-", "/" and "?" (for readonly).
 *
 * UML modifiers are not identical to Java modifiers (e.g. "native" or
 * "threadsafe" are missing.)
