A service can be defined, published and discovered using some type of service inttroduction. The framework has been introduciton to be independent of any particular programming model and other implementation specific semantics.

WS is a software application identified by a URI whose interfaces and binding are capable of being defined,described, and discovered by XML artifacts, and it supports direct interactions with other softwareapplications using XML-based messages via Internet-based protocols W3C: Itmust include a fault code, fault string, and a detailed error message.
