I have a comment on the second requirement in the Note, which reads
"2. The canonical form of an XML document shall be a well-formed XML
document."
Apparently DOMHash does not satisfy this requirement.
However, in the same document it states that its objective as
"The Canonical XML specification aims to introduce a notion of equivalence
between
XML documents which can be tested at the syntactic level and, in
particular, by
byte-for-byte comparison."
and as applications of canonicalization it mentions that
"Such equivalence testing is useful in a number of domains including
digital signatures,
checksums, version control and conformance testing."
For these purposes, DOMHash is clearly useful.
Is this well-formedness of canonical form an absolute requirement, or
is there any way to relax this requirement to accommodate DOMHash as
a candidate of canonical form?
