Right now a new IAccountRegistrationInspector interface has been published.
Please follow #874 and try to implement that inferface, because this will become the new standard for components contributing to the new-user-registration process in AcctMgr. Participants are able to provide additional registration fields, request validation checks or both with minimal effort.
The registration form template already got 2 extensible sections, 'Required' and 'Optional', where new fields will be added. So the previously suggested ITemplateStreamFilter approach, effectively hacking the hack, is neither required nor recommended anymore.
I'll publish the rewritten standard registration checks, that are built-in into AcctMgr, to give some example implementations for early adopters. If you need support for your plugin, follow-up here, please.
