No need to upgrade to solve this specific problem. XMLmind XML Editor, whatever its version, cannot work without knowing which are the start elements of a RelaxNG grammar. You attempt to use in XMLmind XML Editor a set of RelaxNG schemas which are just *building* *blocks* (this is clearly documented in Elkera's "Guide to BNML Schema configuration.pdf") and as such, it simply cannot work. --> Please contact Elkera and ask them to provide you with an *end* *user* schema, one that specifies one or more start elements. This is required by the RelaxNG standard. Excerpts of http://www.relaxng.org/compact-tutorial-20030326.html (recommended reading) --- A grammar pattern contains one or more definitions. Each definition associates a name with a pattern. Inside a grammar, a pattern consisting of just a name references the definition of that name in the grammar. The name start is special. A grammar pattern is matched by matching the definition of start. A grammar pattern must define start. --- --> If this is not possible, then please add yourself a start element at the beginning of bnml-standard.rnc, something like this: --- grammar { start = document|contract|correspondence ... --- Note that [1] I know nothing at all about the BNML vocabulary [2] I just guessed (but I'm not sure) that document, contract, correspondence are good candidates for being start elements (that is, the root elements of the documents you are going to author using XMLmind XML Editor).
