Information exchange: An agreement among people

[ 1 ] XML stands for eXtensible Markup Language. Data is stored in XML documents. XML is actually an agreement among people (programming people) to store and share textual data using the same method.

[ 2 ] Literacy is actually an agreement among people to store and share textual data using the same method.

[ 3 ] Communication is actually an agreement among people to store and share using the same method.

[ 4 ] Communication is actually an agreement among people to share information using their preferred cognitive methodology (mental processing and way of remembering) and using a common format during the exchange. (format can mean any norm -type of body language, short or long sentences, Elizabethan English, to 1960's era NASA/AT&T english technical.)

[ 5 ] Communication is actually a disagreement among people on the agreed upon method of communication.

I prefer to operate with the goals of [ 2 ] and [ 4 ], the others plunge into an abyss of contention.
