Hej, Developing a XML grammer for configuring J2EE resources (via JMX) which is translated into an Ant build file. Want to keep the set of XML elements to a minimum and look into the idea of assigning meaning/context to elements if attributes are present or not (or in certain combinations). For example, the major J2EE managed objects are "resource", "deployable", and "properties" elements designated as children to either "domain" or "subdomain" nodes. All managed object declarations which are children of "subdomain" nodes are restricted to reference (via IDREF attribute) a managed object with a "domain" parent (containing an ID attribute). This pairing of "referencing objects" to unique managed objects (i.e. "pattern objects") is done to administrate the definition of managed objects from the domain only. Anyway the domain nodes could also have "complete" managed objects without ID or IDREF attributes and thus representing a complete definition of a managed object. Depending on which attributes are present and which parent an element has determines the context/intention/meaning of the element. Is this alright? Or should XML elements solely inherit their meaning from element type declarations. Read in the "W3C Recommendation" that quote "An element type declaration constrains the element's content". / Matthew Young
