.IX Subsection "DESCRIPTION"
This module gives you a trait to manage a list of \s-1RDF\s0 resources
typically used in an object position in an \s-1RDF\s0 triple. When declaring
attributes, you may use \f(CW\*(C`traits =\*(C'\fR ['ObjectList']> alone in which
case it'll give you a arrayref of strings and the methods to push to
the array, list all strings in the array, and to check if it is
empty. These are created by prefixing \f(CW\*(C`add_\*(C'\fR, \f(CW\*(C`all_\*(C'\fR and \f(CW\*(C`has_no_\*(C'\fR
to your attribute name, respectively.
.PP
If you have an underscore in the beginning, the attribute will not
itself be a method, but you can still use the non-prefixed attribute
name as argument to the constructor, and you will have the same methods as above.
.PP
You may also give a \f(CW\*(C`isa\*(C'\fR argument to the attribute. In that case,
you may set the arrayref to contain something other than strings, like
in the example above.
