The value argument to access_allowed, acl_mask, etc.

[Julio Sánchez Fernández <j_sanchez@stl.es>]

I am trying to write some documentation for the access control
system of OpenLDAP 2.0 and I find some things that confuse me.

In particular, what is the purpose of the attribute value
argument to the acl routines?  Are they for future expansion?
Because I cannot find how to set it nor where is it checked...

Thanks,

Julio
