Quoting from
Canonical EXI
W3C Proposed Recommendation 26 April 2018

This version:
Latest version:


Any EXI document is part of a set of EXI documents that are logically
equivalent within an application context, but which vary in physical
representation based on differences permitted by the [EXI Format 1.0].
This specification describes a relatively simple method for generating a
physical representation, the canonical form, of an EXI document that
accounts for the permissible differences. An example of the applications
targeted by this specification is one that needs to guarantee
non-repudiation using XML Signature yet allows certain flexibility for
intermediaries to reconstitute the documents before they reach final
destination without breaking the signatures. Note that two documents may
have differing canonical forms yet still be equivalent in a given
context based on more elaborate application-specific equivalence rules
which is out of scope of this specification.
