The False Security of Closed XML Systems

Creating and using XML documents in a closes system gives a false sense of “All’s Well”. A Closed XML system is one where a single party creates and uses the XML documents. Certainly this happens all of the time. We all create little XML documents with one-off throw-away models for one task or another that only we use. These documents will not be the focus here. When documents are created in a closed XML workflow and sent to another entity - such as an archive - for reuse, publishers can quickly learn that the content they have been accumulating is not useful for anything outside of their system and may not be useful if their own systems are upgraded or changed.
The checks and procedures that must be put in place to support XML interchange between entities should be applied within closed XML systems to keep the content usable and useful.
