Absolutely not. :-)

What I mean by roundtrip would be defined by the XTM conformance
section, but basically it would mean that the XTM input and the XTM
output when deserialized according to spec would produce logically
equivalent SAM instances.

| write it ? ;-)

The OKS already has a canonicalizer as part of the API. It's used in
the OKS test suite and we have a command-line tool for accessing it.
We could also make it available in the Omnigator once the new CXTM
spec is ready and the canonicalizer is rewritten to match it.
