Isn't this a repeatable model group? > Or isn't (#PCDATA | stagedir)+ a legal model group in XML? The message should have read "#PCDATA in model group that is not optional and repeatable". The draft XML spec allows mixed content only as an optional and repeatable OR group, where #PCDATA is the first member. By the way, you gain nothing by using "+" instead of "*", since #PCDATA can be an empty string. For example, in full SGML, the following would satisfy (#PCDATA | stagedir)+ as well as it satisfies (#PCDATA | stagedir)*: <line></line> All the best, David -- David Megginson ak117@f...
