Changes additional information / documentation of a method in the EDMdatabase. The purpose of the user defined method signatures is to provide information about the methods and their input parameters to the users. The methods in question are Express-X mapping schemas and query functions. This is the only way to add classification and description to a query function method. For Express-X schema maps, this information may also be given by xpxDefineMethodSignature.
