Schemas describe types for primitive or structured data. XML Schemas are an XML vocabulary that describe the rules that XML business data must follow. XML Schemas specify the structure of documents, and the data type of each element and attribute contained in the document.
You use XML schemas as references for WSDL resources. To learn more, see Viewing and Changing WSDL Details and Resolving Unresolved WSDL References. You can also use XML schemas in the Message Flow of proxy services to validate an element specified with an XPath expression. To learn more, see the description of the Validation action in Validate.
The following table lists the XML Schema pages you can access from the Resource Browser and Project Explorer modules. The tasks and help topics associated with each are provided.
The Summary of XML Schemas page allows you to view a list of XML schemas. Schemas describe types for primitive or structured data.
