Email me the file please, and I will take a look at it.
The problem with the IMAGE content item may be that you do not
have the require concept name for the IMAGE perhaps; it is
required to be (113795,DCM,ï¿½Acquired Imageï¿½), otherwise it
doesn't match the template.
The Device Observer UID error is probably spurious; this content
item was added in CP 1065 and I may have missed adding it to the
validator. I will check and let you know when I have a new version
of the validator if this is indeed the problem.
