The schema parser must have support for regular expression facets.
模式解析器必须支持正则表达式。
Because an XML Schema is itself an XML document, you can write a style sheet that converts the enumeration markup into the regular expression you just looked at.
因为XML Schema本身是XML文档，所以可以写一个将枚举标记转换成您刚刚看到的正则表达式的样式表。
The value of the test attribute of the xs: assertion element facet is an XPath 2.0 expression or XPath 2.0 subset as defined by the XML Schema 1.1 specification that evaluates to either true or false.
如xml Schema 1.1规范定义的那样，xs： assertion元素facet的test属性的值是一个XPath 2.0表达式或XPath 2.0子集，其值为true或false。
