/**
 * Enumerated types for various J2EE versions.
 *
 * Be careful with the compareTo method of this class. It is there for comparing
 * like versions (e.g. servlet 2.3 versus 2.4) only, but there is no type safety
 * to prevent doing dumb things like comparing J2EE 1.4 with servlet 2.3.
 *
 * Perhaps I can think of a better design in the next version.
