ETSI EN 319 132-1规定了XAdES数字签名。XAdES签名建立在XML数字签名[1]的基础上，通过合并签名和未签名的限定属性，这些属性在许多用例中满足某些常见要求（例如，数字签名的长期有效性）。本文档指定了上述限定属性的XML模式定义，以及将它们合并到XAdES签名中的机制。本文件规定了XAdES基线签名的格式，当电子文档中使用的数字签名明确需要互操作性时，它提供了适用于广泛社区的电子程序和通信的广泛商业和政府用例所需的基本功能。 本文件定义了四个级别的XAdES基线签名，以满足增量需求，从而在长期内保持签名的有效性，以某种方式，某个级别始终满足其以下级别的所有需求。每个级别都需要存在特定的XAdES限定属性，并对其进行适当的分析，以尽可能减少可选性。XAdES数字签名的创建、增强和验证程序超出范围，并在ETSI EN 319 102-1[i.6]中规定。ETSI TR 119 100[i]中提供了关于创建、增强和验证XAdES数字签名的指南，包括本文件中定义的不同属性的使用。 11].本文件旨在支持不同监管框架下的电子签名。注:本文件中具体规定的XAdES数字签名旨在支持电子签名、高级电子签名、合格电子签名、， 电子印章、高级电子印章和符合法规（EU）的合格电子印章 第910/2014号[i.1]。

ETSI EN 319 132-1 specifies XAdES digital signatures. XAdES signatures build on XML digital signatures [1], by incorporation of signed and unsigned qualifying properties, which fulfil certain common requirements (such as the long term validity of digital signatures, for instance) in a number of use cases.The present document specifies XML Schema definitions for the aforementioned qualifying properties as well as mechanisms for incorporating them into XAdES signatures.The present document specifies formats for XAdES baseline signatures, which provide the basic features necessary for a wide range of business and governmental use cases for electronic procedures and communications to be applicable to a wide range of communities when there is a clear need for interoperability of digital signatures used in electronic documents.The present document defines four levels of XAdES baseline signatures addressing incremental requirements to maintain the validity of the signatures over the long term, in a way that a certain level always addresses all the requirements addressed at levels that are below it. Each level requires the presence of certain XAdES qualifying properties, suitably profiled for reducing the optionality as much as possible.Procedures for creation, augmentation, and validation of XAdES digital signatures are out of scope and specified in ETSI EN 319 102-1 [i.6]. Guidance on creation, augmentation and validation of XAdES digital signatures including the usage of the different properties defined in the present document is provided in ETSI TR 119 100 [i.11].The present document aims at supporting electronic signatures in different regulatory frameworks.NOTE: Specifically but not exclusively, XAdES digital signatures specified in the present document aim at supporting electronic signatures, advanced electronic signatures, qualified electronic signatures, electronic seals, advanced electronic seals, and qualified electronic seals as per Regulation (EU) No 910/2014 [i.1].
