I agree with this, and yet the Andrew is not the only XSLTer who faces requirements for particular syntactic forms in the output serialization, for whatever reason.

In my experience these are best handled in a post-process. If you know which serializer you are using (and processors generally come with their own), this can even be done in XSLT ... making allowance for a couple of little hacks or workarounds, such as comments or PIs (or spaces, as Andrew says) to split open elements you don't want collapsed, etc.
