The XML returned by GetDocumentation from the EspaceMetaModel extension does not return the Advanced properties of REST method input and output parameters (both consumed and exposed). I need these, as I want to auto-generate REST API documentation for exposed REST services, and it's vital to know the values of the "Send In" and "Name in Request/Rsponse" properties. Is there a way to retrieve these Advanced properties? If not currently, can it be added to EspaceMetaModel?
