    30 Currently FDO interface supports parameter binding when executing an FdoISQLCommand. Method GetParameterValues() returns a parameters value collection and users can set value for each named parameter. However, MapGuide Feature Service doesn’t provide this capability. This RFC will add two methods into Feature Service API to eliminate this limitation.

    36 The !MgParameterDirection defines integer constants used to signify the direction in which command will utilize the parameter upon execution. Parameter direction values are typically Input, Output, InputOutput and Return, with the default value is typically Input.

    656 This RFC depends on FDO RFC 33 (http://trac.osgeo.org/fdo/wiki/FDORfc33), which improves parameter binding to support specifying parameter direction. If FDO RFC 33 can’t get approved, we will not remove class MgParameterDirection and method MgParameter::SetDirection(...) and MgParameter::GetDirection() in this RFC.
