When no domain exists, the 'Domain name' field is blank and the 'Domain Creation' wizard reads:
'Select an alphanumerical name for the domain to edit.'

There is nothing to 'select' or 'edit', so it would be better if it read:
'Provide an alphanumeric name for the domain.'

The IBM style guide used in documenting says to use 'alphanumeric' (not 'alphanumerical').
