Hi, I've got my schema working quite well at the moment. But it can use some more restrictions. For example when my topic already contains a read-more element, it is possible to insert a read-more element before it. I found out that in DITA it is possible to insert a title element before another title element. After inserting the second title element oXygen shows an error message that only one title element is allowed. The same goes for my schema. I cannot insert the same element after an element but can insert it before it, although only one of the same element is allowed. How can I prevent (if it is possible at all) to insert the same element before the same type of element? For example, this is possible in DITA: <topic> <!-it is possible to insert a title element here, by clicking the right mouse button at the title element and selecting insert before --> <title>The title of the topic</title> <!-it is possible to insert a body element here --> <body/> </topic> Kind regards, Roderik Dernison ________________________________ ---------------------------------------------------------- Aan dit bericht kunnen geen rechten worden ontleend.
