Hence, validation can entail a large performance cost if a validating processor needs to parse and build an in-memory representation of a schema before validating each XML document.
因此，如果在验证每个XML文档之前，都要构建模式的内存中表示，验证可能造成很大的性能代价。
Normally, an application has a limited set of schemas, and therefore wants the processor to build an in-memory representation of a given schema once and use it to validate documents.
通常应用程序只使用有限的模式，因此希望处理器只构建一次给定模式的内存中的表示(in - memory representation)，然后使用它验证文档。
Designers need to keep in mind the quantization errors that result from the fixed-point representation of Numbers on a fixed-point processor.
设计人员需要关注定点处理器中因定点数表示法而引起的量化误差问题。
