Actually, there may be another reason why I am getting the concatenated reference. I can't find a rule without a dash, so I'm considering the possibility there is no rule which matches the markup in this context, therefore the text within the <dmrefaddressitems> markup is rendered as it is, which turns out to be, no spaces. This is the same problem I think as my issue with superscript, the markup is there but there was no rule to match, so the character data was simply output as it was.
