Yes. XMLxt adds a floating palette to the QuarkXPress environment providing access to functions of the XTension. Autopage can invoke these functions automatically during the pagination process, and supports batch export of XML-coded files with XMLxt loaded. Because hidden XML codes can be inadvertently modified or deleted during editing, XMLxt provides functionality for checking that the existing tags are well formed. No other XTensions are required for XMLxt to work, and XMLxt does not interfere with the operation of other XTensions.
