For the record, I never proposed the computers should declare themselves as
heaters, only that they could. For further information, contact the "Down
Jackets for Freezing CS Students Because Of Cloud Computing Society, University
of Karlsruhe"

The nice thing with flexible modelling languages and metadata is one can
add novel information in the future if it proves to be useful in reality.
