Retrieving subclasses of a certain class

This query supports getting all subclasses of a single class description. It also allows paging.
The following example shows the retrieval of all subclasses and continuous query:
query
	{
subClassDescriptions(repositoryIdentifier: "OS1", 
identifier: "Invoice", 
pageSize: 5)
 {
    			classDescriptions {
      				id
      				name
      				superClassDescription {
        					name
      				}
    			}
    			pageInfo {
     				 token
      				totalCount
   			 }
  		}
}

	query
	{
moreSubClassDescriptions(token: “<insert_token>”)
 {
    			classDescriptions {
      				id
      				name
      				superClassDescription {
        					name
      				}
    			}
    			pageInfo {
     				 token
      				totalCount
   			 }
  		}
}
