The '{db:"record.VAL"}' definition appears in the *configuration* of the calc-Link.

Every new link type (listed at the head of the referenced document) defines its own syntax for JSON configuration. The namespace for the keys in that configuration syntax is completely separate. The fact that the calc link understands a "db:" tag in its configuration does not mean that tag/functionality is available anywhere else, e.g. in the configuration of a different link type or at top level when configuring a field in a database record.

All existing link types (DB/CA, numerical CONSTANT, hardware links from link.h) continue to work as before - otherwise introduction of the link support would have broken all existing applications and databases. (We're not *that* evil.)

Cheers,
~Ralph
