>This would seem to be an aspect of a more general problem.
I have found this discussion to be very interesting and enlightening. It is especially a problem for those like myself who have just concluded their archaeology studies and are now attempting to put into practice those years of theory which totally outweigh the practice offered by the universities, unless you seek the extra practice yourself.
The degree course I followed omitted any discussion on the issues debated here, so, to a point, one has to follow ones fellow professionals for the correct example of 'how it is done' and hope that they are up to date. Clearly DCC briefs are not up to date, so that is worth checking out.
There is clearly considerable ambiguity between various bodies, and indeed individuals, but that may be something of the strength and value of Britarch to act as a sounding board to clarify matters a little from those who are in 'the know'.
Incidentally, despite much study, I am not a professional in the sense that I earn a living from archaeology, I have the joy of being retired and 'catching up' late in life. This however in no way precludes me from ensuring that the work I am involved with is carried out to the highest standards.
