Urgh, this 'bool' data type is insanity as a way to model
bools in XML.

Rather than

  <is-snapshot>true</is-snapshot>

it should be just

  <is-snapshot/>

The non-existance of the element represents 'false'.

Sadly we can't kill it off from existing schema usage, but
we could deprecate it and make things look for the existance
of the element + back compat code for old docs.

This should be added under a new version block. You should never add to
existing blocks once released.
