Section 2 describes shapes, targets, filters and constraints, then section
3 describes validation as well as the data graph, shapes graph and
validation results.
All constructs described in section 2 are referenced in the validation
definition but any feedback to restructure these sections is more than
welcome.

Based on my understanding,
filters are of course part of the validation process but the term focus
node is used when the nodes reach the constraints of the shape.
As I said, I do not have a strong opinion on this and would be happy to
discuss this further during the next call or hear what others have to say

I'm also a bit concerned about that "iff" - while it is a commonly known

I replaced iff according to your suggestion.

Thanks,
