In section 14.10.1:

The variableDefinition element is used to describe What the evidence is about.

The word "What" should probably have a lowercase "w".

Also, in the same paragraph there are references to "Evidence resource", "EvidenceVariable resources", "Group resources" where "resources" starts with a lowercase "r", but elsewhere in section 14.10.1 an uppercase "R" is used for "resource".  This should be consistent in the page whether upper or lowercase "r" is used.
