 Hi, everybody
I am encountering a validation error when working with an ADL file related to the 'realm' attribute not being found in the flat set of properties in the reference model. I have reviewed the object node definition and constraints in the ADL file, but I am still unable to resolve the error. Can anyone provide guidance on how to resolve this error or suggest any resources or best practices for troubleshooting openEHR validation errors?

There were some out of date archetypes in the test set you are looking at. I have how fixed those. You will need to do a pull from Github on the [adl-archetypes repo](https://github.com/openEHR/adl-archetypes).

hello thomas
Thank you for updating the test archetypes and templates to ADL 2.0.6. I really appreciate it.
