Note that even attributes that contain an IDREF are labeled as XSD: NCName, which performs only the lexical validation of the attribute.

注意，即使包含有标为xsd：NCName的idref属性，也只对属性进行词法验证。

If a FunctionName in a FunctionCall expression is not an NCName (i.e. if it contains a colon), then it is treated as a call to an extension function.

如果FunctionCall表达式中的FunctionName不是NCName(也就是说，如果它包含了一个冒号)，那么就将它当作是对扩展函数的调用。
