I have a little and maybe noob grammar question.

My code :

Greeting :
'module' name=ID '{'
innerElements += ModuleInnerElements*
'}'
;

ModuleInnerElements:
      EntitieStatement
      | InterceptorStatement
;

EntityStatement:
'entity' name=ID '{'
attributes += attributeStatement ((',' attributes += attributeStatement)?)*  
'}'
;

InterceptorStatement:
'interceptor' name=ID '{'
//Not interesting things
'}'

In this case i cant have an interceptor and an entity with the same name


module {
 
entitie customer {
// Attributtes
} 

interceptor customer {
// Not interesting things
}

}

i have an error, obviously, "Duplicate InnerElement", and i dont know the right way for acomplish this.

if i do this in this manner :

My code :

Greeting :
'module' name=ID '{'
Entities += EntityStatement*
Interceptors += InterceptorStatement*
'}'
;

EntityStatement:
'entity' name=ID '{'
attributes += attributeStatement ((',' attributes += attributeStatement)?)*  
'}'
;

InterceptorStatement:
'interceptor' name=ID '{'
//Not interesting things
'}'

I avoid the "name" problem but, there is no the correct sintaxis because i cant make an interceptor and after and entity or an entity,interceptor,entity...

Any suggest?
Thanks, in advance.
