WebSphere Integration Developer now provides a new validator for XML schemas, which define business objects. This validator is enabled by default, but you can use the former validator if you choose.
The XML schema validator (WID) is enabled by default. Although the WID XML schema validator provides better performance under most conditions than the standard XML schema validator in Rational Application Developer, you can change the default setting for this and many other properties used for the development of modules and libraries. Properties that you set for a module or library override general preferences set in the Windows Preferences dialog.
