The developer Stephen Cameron has created a proof-of-concept generic XML editor named "xml.edit.xml" on this basis, hosted at <http://collinta.com.au/xsltforms/xml.edit.xml>. Stephen's idea was to use this for editing conf files and suchlike, and to make it work with mixed content, one has to wrap all text-nodes in an element, since named nodes are required. Stephen has added some sample TEI documents, "punch.xml" and "chinese-dictionary", to illustrate how TEI could be handled. One can also load local files, but larger files will slow down the editor.
