提供了完整的函数集，因此可以把这些值显式地从一种类型转换为另一种类型，将这种转换作为它们在XPath 2.0中操作的一部分。
A full set of functions is provided so you can explicitly convert these values from one type to another as part of their manipulation in XPath 2.0.
泛型相当有用，因为他们提供强制的编译时类型检查，要求更少的数据类型之间的显式转换，并减少装箱拆箱的操作和运行时类型检查。
Generics are useful because they provide stronger compile-time type checking, require fewer explicit conversions between data types, and reduce the need for boxing operations and run-time type checks.
