sdc/external-expression

info Reports an expression whose content is only behind a reference.

What it checks

Looks for Expressions that have a reference but no expression text, such as CQL kept in a Library. Each one is reported once.

Example

This expression has no text, only the reference #calculations, so it was not checked.
