The advantage over using value comparisons is that you don't risk a runtime error.
这种方式较之使用值比较的优势在于不会有运行时错误的风险。
Value comparisons are about relationships between atomic values, and they do not check an entire set.
值比较用于原子值之间的关系，不检查整个集合。
Do not change atomic types (string, integer, etc.) if queries are strongly typed or have value comparisons.
如果查询是强类型的或者需要进行值比较，不要改变原子类型(string、integer等)。
As an alternative to value comparisons, you can use the self axis (denoted by a dot ". ") to express a "between" predicate.
除了值比较，还可以使用self轴(由点“。”表示)来表达“between”谓词。
If you know that a book has at most one price element, you can write the query using XQuery value comparisons, which force the comparison operands to be singletons.
如果知道某个book至多有一个price元素，则可以使用XQuery的值比较来编写查询，这迫使进行比较的操作数是单个数。
BC mode impacts numeric comparisons in two ways: allowing selection of the first member of a set and obtaining NaN for a non-numeric value, rather than throwing a type error.
BC模式对数字比较的影响有两个方面：允许选择集合的第一个成员，对于非数字值返回NaN而不是抛出类型错误。
Comparisons between the measured value and the calculated value of the frequency are made, and the error analyses are also carried out.
将频率实测值与计算值进行比较，同时进行了误差分析。
