Hi Christian,
Thanks for the quick response..

If i have grammar -
Family returns Family:
{Family}
'Family{'
'Name:' name=EString
'}';

Here 'Name:' is keyword. i have imported one file, in that name is empty but tag has been created. So on opening xtext editor for that file, it will print the keyword 'Name:' with empty value.
I do not want to print keyword with empty value. how i can remove it?

strange grammar. maybe you can change it to

('Name:' name=EString)?

btw it that empty "" or is it null (in the model you open)
if it really is "" i am not sure about that. maybe you can customize the serializer
