Retrieving the key from another location using a URI-reference is supported using the RetrievalMethod element. This is also useful if there are multiple signatures in one document, allowing the public key information to be specified only once, and referred to by the other signatures. A key can also be referred to by name. This may be useful in small closed groups, where everyone's key is manually known. The XKMS specification makes use of the XML key information elements for key registration and recovery.
This signed document is called a public key certificate. The certificate can be validated by others using the CA's public key. Therefore, on assuming the CA is competent and trustworthy, the certificate can be used to prove that information verified using the public key contained in the certificate was originally signed by Alice. A certification authority will issue many public key certificates for lots of entities. This reduces the problem of being able to securely obtain the public keys for any of these entities to knowing the public key for the certification authority and being able to trust it.
This allows the precise binary form of the original digital signature to be recaptured when validating without requiring that the original XML document is retained. Canonical XML is based on information preserved by the popular parsing APIs, such as SAX and DOM. The Canonical XML standard allows the canonicalisation of well-formed XML. One such case is the order of attributes within an element. The XML standard states that attributes can be created in any order without changing the document meaning.
