4243 *
4244 * When 2 XSDKey's are compared, the following table can be used to
4245 * determine whether they are equal:
4246 * inc red imp pre ins
4247 * inc N/L ? N/L N/L N/L
4248 * red ? N/L ? ? ?
4249 * imp N/L ? N/P N/P N/P
4250 * pre N/L ? N/P N/P N/P
4251 * ins N/L ? N/P N/P N/P
4252 *
4253 * Where: N/L: duplicate when they have the same namespace and location.
4254 * ? : not clear from the spec.
4255 * REVISIT: to simplify the process, also considering
4256 * it's very rare, we treat them as not duplicate.
4257 * N/P: not possible. imp/pre/ins are referenced by namespace.
4258 * when the first time we encounter a schema document for a
4259 * namespace, we create a grammar and store it in the grammar
4260 * bucket. when we see another reference to the same namespace,
4261 * we first check whether a grammar with the same namespace is
4262 * already in the bucket, which is true in this case, so we
4263 * won't create another XSDKey.
4264 *
4265 * Conclusion from the table: two XSDKey's are duplicate only when all of
4266 * the following are true:
4267 * 1. They are both "redefine", or neither is "redefine";
4268 * 2. They have the same namespace;
4269 * 3. They have the same non-null location.
4270 *
4271 * About 3: if neither has a non-null location, then it's the case where
4272 * 2 input streams are provided, but no system ID is provided. We can't tell
4273 * whether the 2 streams have the same content, so we treat them as not
4274 * duplicate.
