9.1 Introduction
The mandatory DescribeProcess operation allows WPS clients to request a full description of one or more processes that can be executed by the Execute operation. This
description includes the input and output parameters and formats. This description can be used to automatically build a user interface to capture the parameter values to be used to
execute a process instance.

A request to perform the DescribeProcess operation shall include the parameters listed and defined in Table 13. This table specifies the UML data type, source of values, and
multiplicity of each listed parameter, plus the meaning to servers when each optional parameter is not included in the operation request. Although some values listed in the
―Name‖ column appear to contain spaces, they shall not contain spaces.
