Does GT3 and/or OGSI support operation overloading?
OGSI has no notion of operation overloading. Operation overloading was allowed under WSDL 1.1 but it is not allowed in WSDL 1.2. We do not recommend relying on operation overloading as it may cause problems with dynamic systems such as workflow engines. Use separately named operations with different syntaxes, or one generic operation with generic/document-extensible syntax instead.
