- An XML-Signature can apply to a part or totality of an XML document.
- More than one signature may exist over any resource.[Charter, Brown]
- A key use of XML Signatures will be detached Web signatures. In conjunction with XML
facilities (including packaging) signatures may be embedded within or encapsulate XML or
encoded content. [Charter]
- The Signature syntax specification will not specify methods of serialization or
canonicalization. XML content is normalized by specifying an appropriate content C14N
(canonicalization) algorithm [DOMHASH, C14N]; applications are expected to normalize
application specific semantics prior to handing data to a XML-Signature application.
