Hi Rupert
Sorry that I could look at your code proposal for the archetype just
now. Thanks for your proposal.
For now I just did a minimum adaptation to the old code. Mainly
because your code depends on the trunk version api and I would like
the archetypes to be released ASAP.
Also I don't really understand where the enhancement is in your code.
It selectes all Uppercase word but IIUC, the code isn't adding any
enhancement to the selection, maybe just add a RDFS:comment "This is
an uppercase word".
I suggest we look at imprroving the example code after the first release.
Cheers,
Reto
