A question about Wisent-analog to Bison grammar attribute

[Christian Johansson]

Hi!

I'm trying to convert the PHP Parser Bison grammar to Wisent and I have 
stumbled upon a detail that I can't find a solution to.

In 
https://github.com/php/php-src/blob/master/Zend/zend_language_parser.y#L309
the grammar looks like this:

name:
        namespace_name                                { $$ = $1; 
$$->attr = ZEND_NAME_NOT_FQ; }
    |    T_NAMESPACE T_NS_SEPARATOR namespace_name    { $$ = $3; 
$$->attr = ZEND_NAME_RELATIVE; }
    |    T_NS_SEPARATOR namespace_name                { $$ = $2; 
$$->attr = ZEND_NAME_FQ; }
;

My interpretation is that the return value of this block is the name 
excluding the token for the keyword namespace of the separator, but also 
that the return value has attributes attached to, like whether it's not 
fully-qualified, fully-qualified or relative. Is it possible to 
something similar with Wisent grammar?
