Proposed Credibility Signal - Validity

Short Name:  Validity

Definition:  The content complies with (validates 
<https://en.wikipedia.org/wiki/XML_validation> against) a schema 
specified by an international voluntary consensus standards development 
organization <https://en.wikipedia.org/wiki/Standards_organization> (SDO).

I'll miss the next two CredWeb CG meetings but will look forward to 
learning and reporting the results in StratML format here 
<http://stratml.us/carmel/iso/part2/CWCG2020.xml#_ac59639c-3d4e-11ea-a6fb-9d461083ea00>.
