I'd like to improve the export (and import) to handle custom taxonomies properly.
Is it ok to add the (classical) php extension DOM that handles XML documents as a hard dependency to WP?
Until now you guys produce the XML "by hand" (echo & print various strings), whereas using DOM would allow for much more efficiency (including automated serialize / de-serialize).
Thanks for your input. If this should be discussed some place else please let me know.
