[TalentSignal] Other requirements in JobPostings

Hello all, we have four potential properties identified from the 
analysis of the JDX JobSchema+ 
<https://www.w3.org/community/talent-signal/wiki/Comparison_of_JDX_JobSchema%2B_with_schema.org>[1] 
as missing from schema.org that relate to requirements other than those 
for competencies and credentials. These are

  * Citizenship Requirement "Country of applicant's citizenship"
  * Physical Requirement "Resource identifying types of physical
    activity associated with a job"
  * Security Clearance Requirement "Description of any security
    clearance requirements for the job"
  * Sensory Requirement "Resource identifying sensory requirements and
    levels necessary to function on the job including hearing and vision"

Do you agree that these would be useful additions?  Does anyone have any 
data or evidence for how common it is to find this type of requirement 
in job postings?

Might we combine Physical and Sensory? (FWIW, I'm happy to keep them 
separate)

Would you be happy with them all to take text & URL as values: i.e. 
provide values as free text or a link to a description. The exception 
might be schema.org/Country for Citizenship Requirement.

All the best, Phil.
