Product:Software/org/oomodels/converter/WebService

A builtin converter which connects to a web service to perform the actual conversion. This allows third party software providers who do not want to expose their code to us to provide conversion services to oomodels.

This converter is not referenced directly, but via an intermediate format converter page (like this), with additional properties providing arguments for the conversion.

These argument are:
 * ServiceURL - used to connect to the web service (HTTP POST)
 * URLParameterName - the name of the parameter (form-encoded) containing the data to convert
 * ConverterId - always Product:Software/org/oomodels/converter/WebService
