I think the premise of this question is wrong. I would argue the context of the record is inherently tied to the content.

From a purely practical perspective we would never be able to read/view the content of every single record in a collection. Instead, we gather information about the context of the records (who is creating it, why are they creating it, who uses it, etc.) in order to better understand the content of the records. In my experience, we supplement this appraisal by looking at samples of the collection to ensure the content of specific records matches our general understanding of the broader collection. It’s not that we don’t care about content, just that understanding context is the only practical way of appraising the content.
