I like industry standards for several reasons:

1) Validation = Can I look at it and see the form is correct?
2) Verification = Can an external source map the key to the entity?
3) Universality = Does everyone agree on the meaning?  This is the

idea of a trusted source to maintain the standard for me (the laziness principle of programming).

 I think this is more important than familiarity, which is subjective. Received on Sat Sep 04 2010 - 03:30:19 CEST
