Include the correct sequence and study wave in the qc/qi labels.
Create specific numeric response domains where possible. Search for the question in the XML to see if there is a min and max. For example, do not use "how many", if at all possible. Use ranges if possible. (can we add an example please?)
The entire Proxy section should be entered inside a loop, as Proxy questions may be answered for more than one missing household member.
If there is a missing response domain, check the previous waves to see if it's included and use that.
