分布式标识中文翻译稿校对

对分布式标识中文翻译稿核心属性部分的修改意见如下：

核心属性
1、with expected values, and whether or not they are required. The property names in the tables are linked to the normative definitions and more detailed descriptions of each property. 翻译为：“包括预期值以及是否为必需属性。表格中的属性名称链接到每个属性的规范定义和更详细描述。”更准确。
2、Note: Property names used in maps of different types未翻译，翻译为：”注意：不同类型映射中使用的属性名称“
3、DID文档属性表和验证方法属性表中，Value constraints翻译为值约束，服务属性表中，翻译为约束值，需要统一。
4、The id property only denotes the DID of the DID subject when it is present in the topmost map of the DID document. 翻译为：”id属性仅在出现在DID文档的最外层映射（topmost map）中时，表示DID对象的DID。“更合乎中文习惯。
5、The verification method map MUST include the id, type, controller, and specific verification material properties that are determined by the value of type and are defined in 5.2.1 Verification Material. 翻译为“验证方法映射必须包含id、type、controller以及由type的值确定的具体验证材料属性，这些属性在5.2.1验证材料中定义。”更准确。
6、This is done by dereferencing the URL and searching the resulting resource for a verification method map with an id property whose value matches the URL. 这里的defeferencing翻译为“取消引用”，和前面的翻译都不一样，建议上下文保持一致。
7、不知道理解得是否正确，例15中说明验证属性包含三种验证方法，但示例中似乎只包含2种验证方法？
8、Note that the verification method indicated by the authentication property of a DID document can only be used to authenticate the DID subject. To authenticate a different DID controller, the entity associated with the value of controller, as defined in 5.1.2 DID Controller, needs to authenticate with its own DID document and associated authentication verification relationship. 翻译为“需要注意的是，DID文档中authentication属性指示的验证方法只能用于认证DID对象。要认证不同的DID控制者，与controller值关联的实体（如5.1.2 DID控制者中所定义）需要使用其自己的DID文档及其关联的认证验证关系进行认证。”更准确。
9、This property is useful, for example, during the processing of a verifiable credential by a verifier. During verification, a verifier checks to see if a verifiable credential contains a proof created by the DID subject by checking that the verification method used to assert the proof is associated with the assertionMethod property in the corresponding DID document. 翻译为“这个属性在处理可验证凭据时非常有用。例如，在验证过程中，验证者会检查可验证凭据是否包含由DID对象创建的证明，具体方法是确认用于断言该证明的验证方法是否与相应DID文档中的assertionMethod属性相关联。”更准确。
