1. A method of automatically consuming and processing web services, the method comprising: parsing a first document describing a deployed web service to identify a first set of attribute-value pairs describing a first function offered by the web service and a second set of attribute-value pairs specifying instructions for processing result data returned by the first function for rendering in a user interface element implemented by a web service client, the second set of attribute-value pairs including a first attribute-value pair specifying a data type for the result data returned by the first function and a second attribute-value pair specifying a first instruction for processing the result data returned by the first function; constructing an invocation request object for invoking the first function based upon the first and second sets of attribute-value pairs; and processing the result data returned by the first function based upon the second set of attribute-value pairs to generate a set of code executable by the web service client to render a presentation of the result data returned by the first function in the user interface element.
