和urn:uuid:），那么Identifier.system的值必须是”urn:ietf:rfc:3986“。Identifier.value的主要用途是对不同命名系统中的标识符进行映射。因此，为了方便对比，可能会对其值进行标准化处理（例如，删除不重要的空白、破折号等）。如果想显示可读强的文字说明，可以使用Identifier.extention.renderedValue扩展元素。 Identifier.value是严格区分大小写，除非指定的Identifier.system明确说明在其命名空间域内的值不区分大小写。" /> </element> <element id="Identifier.value.extension"> <path value="Identifier.value.extension" /> <slicing> <discriminator>
