Whenever the predicted symbol is unique, there is no need to encode it as the decoder generates the same model from the DTD and thus can generate the unique expected symbol.

只要预测到符号是独特的，就不需要对其进行编码，因为解码器从DTD生成相同的模型，从而可以生成独特的预期符号。

If there is no DTD specified in the XML, the whitespace is not ignorable.

在XML中如果没有指定DTD，那么空格是不可忽略的。

Let me repeat that: If there is no DTD, the whitespace is not ignorable.

我再次重申：如果没有DTD，空格是不可忽略的。
