TAP and validation

[kcoyle]

We may not wish to go into this, but I think that questions will come up about how TAP relates to validation.

Here are the examples that I have played around with, very informally, in some Google Docs. They should be open for commenting and editing:

• TAP repeated properties
• Shapes and cardinality
