Hi, I think the forms-like editing in Author mode is fantastic. One thing I like being able to do is having a pull-down listing valid values for element or attribute contents. One thing I have a need for -- to have the choice of valid values specified dynamically, in the document itself or close by. I can specify a rule in Schematron that checks whether arbitrary (key) relations hold in a document (or across two or more documents), but I wonder how I can get oXygen to read the permissible values (however they are defined and constrained, for example as a set of attribute values in metadata) and pop them up in a picklist. Essentially this is like an ID/IDREF requirement, only generalized, and specifiable using XPath. Is there any hope for me? Could I sneak some kind of function into the CSS that oXygen uses to configure the pick lists, and achieve this, using XPath?
