View source for Industry a standard code

{{Navigation}}'''Issue description:''' Provide a means of giving the industry a standard code.   From [[Comparison of JDX JobSchema+ with schema.org]]

'''Discussion''': mail list [https://lists.w3.org/Archives/Public/public-talent-signal/2019Nov/thread.html Nov 2019], thread on  properties relating to employer information.
* Currently JobPosting has a property for [https://schema.org/industry industry], (the industry associated with the job position) but this can only be text so codes like those in NAICS or ESCO would be difficult to interpret.

==Propsal==

Suggest adding DefinedTerm to range of <code>industry</code> property.
