I dont think anyone expects every reponse of the server to be validated.
But people start writing their own manipulation, retrieval, server programs
and from my own experiences its sometimes hard to tell whether this
specific XML i created is still within the expected boundary. So I am in
favour of a possibility to validate xml output from time to time
against a DTD - I have no problems if the DTD is a moving target and
people get told something changed. But currently there is nothing to
check against (except loading into josm and trying to interpret the
error message). But what about the change files?
