RE: [xml-dev] Evaluation Criteria for Markup Languages

["David Lee" <dlee@calldei.com>]

If this is actually about *physically shipping* property then the name/address issues are pamount.
I recommend looking at what various shippers allow, such as FedEx, UPS, Postal Mail etc.
Its amazing how both limited and different they are.   Even within a given shipper the rules change depending on the service level (historically due to aquireing different companies for different service levels like Ground vs INTL).

It doesn’t matter if your address model is extremely rich (say allow native Chinese characters in Unicode and 10 address lines) if the shipper requires 7 bit ascii , 2 address lines max of 35 "bytes" each.

I would suggest focusing on what the information ultimately has to be used for.
You may find you need duplicate sets of information.  For example a native language shipping address along with a 'primative' foreign ascii latin address.

1.  Isn't this the same problem as railroad schedules across different time zones before time zones or trying to send mail to an address in London?

2.  The typical solution is the global solution:  ignore local traditions without violating them, that is, as in the case of unversal time, don't use the local time traditions.

We've all had to build in code for local naming traditions, addresses, heck, even had to change the colors on the web page because a new party took power.  We've had to go through hundreds of pages of documents to ensure there are no references to the star of david or  
israel (yes, we do).   Again, multiple authorities over a process or  
data set is the recipe for chaos in integrated systems.

We solved the problem for hypermedia by accepting Berners-Lee's admonitions to let the links snap and accept one universal getting-a-file-and-mailing-it-back addressing technology.  It was simpler than letting everyone make exceptions and it uncovered enough unknown exceptions to create careers for some of us.  K.I.S.S.  
sometimes comes at the cost of frosting the locals.   Consensus can  
cost too much.

Something of a challenge then: what is the simplest possible way to create addresses that will operate across the most addressed recipients where in fact, you have to identify both the address and the recipient and in this case, they CAN'T be the same names?
