use of the application for example a gui element pointing to an u201c invocable parameter u201d 14 will contain the necessary information to launch its u201c assist context u201d 14 a in order to instantiate that parameter e g a wsdl operation parameter could be represented as lt operationparameter filename u201c f seqflow u201d gt a u201c help context u201d property 18 can also be defined to represent a basic help facility for using a parameter and can be contained in plain text file s if tooling instructions are not available for that parameter the u201c name u201d property 19 e g xml tag can be used to identify the parameter as used in a u201c p instance u201d 100 the u201c parameterization framework u201d 20 provides a programmatic means to create u201c p instances u201d 100 utilizing the parameterization model 10 for a software application under this framework parameterization is initiated using the u201c control context u201d 17 for the modeled parameter to invoke execution of a program method named u201c parameterizable u201d 21 in order to implement the parameterization details using a pre defined selected set of u201c invocable parameter u201d object classes 14 for realizing instantiation of the parameter as described above an u201c invocable parameter u201d 14 or u201c informational parameter u201d 13 or u201c referential parameter u201d 12 type in an application can be modeled for use by the u201c parameterizable u201d program method and the application can use the parameterization model framework to add u201c p instance u201d parameterization points to the ui as shown in fig2 except for optional use of an u201c inplace parameter u201d 15 the model may not specify where parameterization.
