Configuring C14N for NameID lookup

That’s what I thought which is why I mentioned it.   If you want to
contrast, NameIdentifierCanonicalization does it the old way (although this
is non deployable because the Predicate is non static), whereas the
NameIDCanonicalization has the static Predicate, but that is what does the
format comparison.

Deploying the NameIdendifierCanonicalization would consist of moving the
format comparison up to the main bean from the predicate, declaring the
formats as a named bean in the user config and injecting this by reference
in the flow files (in system config).  R5349 of NameIDCanonicalization has
an example of the first.
