- Run the 'max' check always, even 'exists' option is set to false, let the parent class decide if exists validation is needed (for namespace type this is just moved, parent does not support that setting) - Validate given namespace to be numeric and cast the value, on new php the meaning of the condition ´'text' < 0´ changed (https://wiki.php.net/rfc/string_to_number_comparison) - Pass the max value as formatted number to the message - Return message as object, allows the html builder to choose the correct format to display - Make 'required' to work on namespace type and title multiselect type - Combine multiple errors from each validation step and show as bullet point list, if multiple errors exists (not for namespace type, there are no nice messages to show) Change-Id: I1f6df50277e6911b2f0ac36fdbd071407437fc78
