In this paper we present tools that provide an easy way to edit XML content directly on the web, with the usual benefit of valid XML content. These tools make it possible to create content targeted for lightweight web applications. Our approach uses (1) the XTiger template language, (2) the AXEL Javascript library for authoring structured XML content and (3) XSLT transformations for generating XML schemas against which the XML content can be validated. Template-driven editing allows any web user to easily enter content while schemas make sure applications can safely process this content.
