We're seeing a lot of traffic at the moment from people asking for tweaks to
serializers to make them avoid using constructs that recipients can't
handle. For example, there's a thread on the JDOM list from someone who
can't cope with CDATA sections (banned apparently because they are deemed a
security risk!), and I had one recently on the Saxon list from someone who
wanted particular line endings, and another not so long ago from someone who
didn't want empty element minimization. Minor post-processing edits seem to
be beyond the skill level of the people raising these posts; and they
shouldn't be necessary. People should accept XML. I intend to continue
responding to such requests with "tell your customer to install a real XML
parser".
