[oe] tinderbox packages

[Frans Meulenbroeks]

In my dir I have these bb files:
docbook-sgml-dtd/docbook-sgml-dtd-3.1-native.bb
docbook-sgml-dtd/docbook-sgml-dtd-4.1-native.bb
docbook-sgml-dtd/docbook-sgml-dtd-4.4-native.bb
docbook-sgml-dtd/docbook-sgml-dtd-4.5-native.bb

However tinderbox only shows the first one in the list of packages.
Does this mean the other ones are never build?
Or does something need to be done to add them to tinderbox?
Or is this a bug ?

Any wiz around who can shed a light?
