I think having this in a standardized way in TCL helps a lot.
Furthermore it would help us with writing a quick M$ Access like frontend within OpenACS (you just define the content type with it's attributes and OpenACS offers you templated/list-builded create,view,edit,search pages that store the content in the CR with all the benefits involved).
This would make it easier for the occasional user to quickly create a database for his stamp collection and make use of all the great features OpenACS has to offer.
Last but not least, TCL is easier than prozedural database language and should lower the barrier for using the content repository considerably.
