Catmandu::Fix::Condition::marc_spec_has - Test if a MARCspec references data

       Evaluate the enclosing fixes only if the MARCspec does reference data.

       Does the same like  marc_has but uses MARCspec - A common MARC record path language.

       See MARCspec - A common MARC record path language <http://marcspec.github.io/MARCspec/> for documentation
       on the path syntax.

marc_spec_has(MARCspec)
       Evaluates to true when the MARCspec references data, false otherwise.
