I've tried your suggestion above, but I get an XML parsing error ("xml 
declaration not at start of external entity") when I either try to 
update my extension or load update.rdf directly in the browser.

I tried setting the variable $local_conf_mime_types = ON in the 
local.conf file for my project - but that had no effect.
