The XMLWriter module has been part of core PHP for ages and should be perfectly serviceable, at least based on the sample NCIP XML messages I've perused. It's a simple wrapper around libxml2 and it worked well for my needs in generating MARCXML in File_MARC. Similarly, for working with incoming XML both SimpleXML and XMLReader are part of PHP core; SimpleXML offers a pretty friendly API and it's what I used to read MARCXML in File_XML.
