Commands are declared in an XXE configuration file bound to a document type, not the in CSS style sheet (see http://www.xmlmind.com/xmleditor/_distrib/docs/poweruser/ar01s01.html ). This is described in http://www.xmlmind.com/xmleditor/_distrib/docs/poweruser/ar01s04s02.html (<cfg:command>) and in http://www.xmlmind.com/xmleditor/_distrib/docs/poweruser/ar01s04s01.html (<cfg:binding>). But I don't see how writing a command would solve your problem... You'll have to wait until XXE V2.4 is released. As a ``side effect'' of implementing multi-file documents, XXE V2.4 will allow to very easily toggle the editability of an element (of a document subtree, in fact). When you'll be able to code "element.setReadOnly(true)", writing a very simple documentHook defining a documentOpened(Document) method will solve your problem (see http://www.xmlmind.com/xmleditor/_distrib/docs/dev/ar01s06.html ). In this method, you have access to the document just after it has been opened. You can traverse its elements and, according to your business rules, turn off the editability of certain elements.
