Group
A Group is defined in the following WSDL:
The WSDL for the group complex type contains all the fields one is used to seeing in the web interface when creating or editing a group. The required fields are as follows: group name and role.
Some things to note: when specifying the groups's users, list the users as a semi-colon delimited list, i.e. "user1;user2;user3". When specifying the group's role, one only need specify the highest role for that group due to the fact that roles are cumulative. The roles are defined by the following simple type restriction in the WSDL:
Also, note that users in this group will inherit that role if it is higher than the explicitly defined role for that user.
