Creating Subgroups via SDK


I am trying to create an subgroup via SDK. Therefore I use the SWQL-Studio.

For testing purposes I created a group 'Test' via WebGui this Container/Group has the ID 23.

Now I want to create an Subgroup:

But I dont know how to fill the "Name" and "Definition" tag at memberDefinitions.

<ArrayOfMemberDefinitionInfo xmlns:i="" xmlns=""><MemberDefinitionInfo><Name>???</Name><Definition>???</Definition></MemberDefinitionInfo></ArrayOfMemberDefinitionInfo>
