- Common Vocabularies Establishing common vocabularies makes it easy to build software that processes information according to a clearly defined set of rules. The larger the audience using the same vocabulary, the larger the audience.
- Formal Sets of Rules Because machines (computers) will be doing most of the XML processing, expressing those vocabularies in a form that computers can understand is important. The formal description must be regular, unambiguous, and relatively easy to process.
- Building Contracts On the human side of the information interchange equation, formal descriptions of vocabularies can provide a core set of rules for all participants in a series of transactions. Schemas can make it clear which kinds of information are required or optional for which kinds of transactions.
