Hi Alexander,
You are now able to create the Structure and set the cardinality also in NetWeaver CE.  I thin the following steps will be helpful for you.
1. Create a CAF project called firstcaf.
2.Create an entity service within the project called Customer.
3. Now expand modeled.
4. Then right click on Data Types. Here you will get the option "New Structure".
5.Now select New Structure, One popup will appear then enter the Structure name called Address and click ok.
6. Now You will get your Address structure under Complex Types.
7.Double Click on Address. In right hand side you will get the Address structure for editing.
8.Now from left hand side(Existing Type) expand caf.core and add your required attribute. In right hand side (structure Field) you can edit the name of attribute. suppose for Address structure I have added two field phone and mobile (both are short text ). save it.
9. Now switch to Composite Application Explorer and expand Business Objects ->Customer -> Customer->Customer. and double click on it (Customer).
10. In right hand side expand project firstcaf ->modeled. Now you will get your structure here, In my case I will get Address structure. Now select your structure and  click Add button. Structure will go to right hand side(Structure Fields).
11. If you want to change the cardinality it is very simple. Select The Structure from right hand side(Structure Fields) and in bottom side click on property. Now you will get the Cardinality field. you can change it as you like.
