Hi Gerard,

I would agree with most, of not all of your definitions.

I can forsee use for templating being done on single archetypes to define
local or professional constraints e.g minimum datasets or 'good-practice'
guides.

I would regard a patient mandate archetype as an Evaluation but we may have
a different idea of what constitutes a patient mandate. Can you give a
specific example - ? something like 'Does not wish to be resuscitated in
event of cardiac arrest?'
