=head1 NAME

X11::Xlib::XID - Base class for objects wrapping an XID

=head1 ATTRIBUTES

=head2 display

Required.  The L<X11::Xlib::Display> where the resource is located.

=head2 xid

Required.  The X11 numeric ID for this resource.

=head2 autofree

Whether this object should control the lifespan of the remote resource,
by calling an Xlib Free/Destroy function if it goes out of scope.
The default is False, since this base class has no idea how to release
any resources.
