若m中任意两个子集，或者它们无共同元素，或者一个是另一个的子集，这样的M称为分类集。
M is called taxonomic class of sets if. for every two elements of m, either they are disjoint, or one is a subset of the other.
您可以使用各种XQuery构造向XML数据应用相似度监测，以便按共同元素(比如作者名、数据来源，等等)找到数据。
You can apply similarity detection to XML data using various XQuery constructs to find data by a common element such as author name, source of data, and so on.
上述共同的元素是一个例子，尽管它是唯一的例子。
The aforementioned common elements are one example, although hardly the only example.
