I wan to add Annotations to the grammar.
I have tried the following code

grammar org.lunifera.metamodel.dsl.entity.Entity with org.eclipse.xtext.xbase.Xbase

generate entity "http://www.lunifera.org/metamodel/dsl/entity/Entity"

import "http://www.eclipse.org/xtext/xbase/Xbase" as xbase

...

Entity:
       	(annotations=Annotation) 
	'entity' name=ValidID ('extends' superType=JvmParameterizedTypeReference)? '{'
	property+=Property*
        ....
	'}';

Property:
	varType= 'var' type=JvmTypeReference name=ValidID ';';

enum Annotation:
	embeddable='@Embeddable' | cachable='@Cachable'
;

In my DSL I want to can write:

@Embeddabel
entity Person {
....
}

But I have Problems with the Annotations.
They appear not in the Content Assist of the IDE
Also entity appear not in the Content Assist of the IDE

I use Xtext 2.3

IIRC, you do not get automatic content assist for enums the same way you
do not get content assist to write an integer value.

Think there are a couple of posts and answers on that topic in this forum.
