But the error in question would show up after the encoding
declaration had been processed -- well after! -- so the
XML processor itself would no longer need involvement.

The non-normative "detection" can't involve the error ...
surrogates can't appear within encoding declarations.

In any case, it's OK for conformant processors to reject
UCS-2 out of hand, eliminating all possibility of such
an error in any case!
