Creating Subgroups via SDK

Hi,

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:

<ArrayOfMemberDefinitionInfo xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.solarwinds.com/2008/Orion"><MemberDefinitionInfo><Name>???</Name><Definition>???</Definition></MemberDefinitionInfo></ArrayOfMemberDefinitionInfo>
