List of strings as a concept property

Is it possible to have a list of primitive types (e.g string/integer) as a concept property? I would like to do something as follows: 

concept SomeConept extends BaseConcept                                                                                                                
                                            implements <none>                                                                                                                  
                                                                                                                                                                               
  instance can be root: false 
alias: <no alias> 
short description: <no short description> 
 
properties: 
path : list<string>
 
children: 
<< ... >> 
 
references: 
<< ... >>
                                                                                                            httpVerb : string                                                  
                                                                                                                                                                               

If no what is the reason that there is no possibility to do this?
