Common XML attributes |
All XML encoded WFS requests include an attribute called version. The mandatory version attribute is used to indicate to which version of the WFS specification the request encoding conforms. For more information about versions, please refer to Version numbering and negotiation.
For WFS 1.0.0, the default value of the version attributed is set to 1.0.0. For WFS 2.0.0, the version number by default is 2.0.0.
All XML encoded WFS requests include an attribute called service. The mandatory service attribute is used to indicate which of the available service types, at a particular service instance, is being invoked. When invoking a web feature service, the value of the service attribute shall be WFS.
The purpose of the handle attribute is to allow a client application to associate a mnemonic name with a request for error handling purposes. If a handle is specified, and an exception is encountered, a Web Feature Service may use the handle to identify the offending element.
