More than one mandatory aspect for the Custom Type

[bisana]

Hi
  For a Custom Document  Type, can it have more than one mandatory aspect, how much aspects can I add as mandatory in the created custom document type.
How could I add it, should I add like this

<mandatory-aspects><aspect>cm:generalclassifiable</aspect><aspect>sc:webable</aspect><aspect>sc:productRelated</aspect></mandatory-aspects>‍‍‍‍‍‍‍

or should I add it like

<mandatory-aspects><aspect>cm:generalclassifiable</aspect></mandatory-aspects><mandatory-aspects><aspect>sc:webable</aspect></mandatory-aspects><mandatory-aspects><aspect>sc:productRelated</aspect></mandatory-aspects>‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Guidance and advice requested
Thanks

Did not get a error, Since I did not get the error I assume that this the way to add multiple mandatory aspects to the Custom Types.
If I am wrong or If any better way is there please guide me
thanks
