create & use attributes.xml file #26

AD only gives a boolean on the entire file, acceptable or not. No coaching on what might be an error. There is an XML Schema available to use with xmllint.

Does areaDetector give a warning/error if any of the attributes cannot be read, e.g. typo in the PV name?

The boolean for the entire file is for XML syntax errors, not whether the PV is actually reachable. It is not an error for a PV to not be reachable, because the IOC hosting it may be down at the time the AD IOC is started, but it may become reachable later. It is thus not possible to detect typos in PV names.
