RE: [xml-dev] Include data that may be objectively generated someday?

["Cox, Bruce" <Bruce.Cox@USPTO.GOV>]

When designing the DTD's for published patents, we included markup for well-defined constructs specified in the rules for patent filing, examination, and granting.  Some of that markup was speculative, in the sense that there were no systems in existence that would exploit the markup.  Consequently, the contractor converting content to XML for publication was instructed to not apply some of the markup, purely for the cost benefit.  Ten years later, we're building systems that would have exploited that markup, were it there.   Can't win them all.

How about: don't publish what you don't own?

Publishing schemas that include meaningless definitions has an analogue in software development, which is writing untestable code: ie code designed to handle a circumstance that has not yet occurred and may never occur.  It's always a bad idea.  Seems to be generated by people with clever ideas about future-proofing, but it seems as if we are wrong more often than not about where the future is headed.

One practical approach to dealing with this tendency is to insist that any schema definitions be backed up by requirements, functional specifications, sample data and use cases, together with tests to prove the data functions as intended in at least some dummy test environment.  
Just like real requirements! The proponents either pay the freight, if the feature is really deemed to be important, or it gets dropped as low priority.
