Remarks

Placeholders are written in braces and are matched against the scope of the request without regard to case, for instance Server=sql.example;Database=app-{tenant}. The placeholders {purpose} and {storage} are always available. A placeholder without a value fails rather than producing a connection to the wrong database.
