Hi Ken
My understanding of the patch rule here is that
if you supplied a Disability
element (capital D) in the input resource, then the disability
attribute (small d, datatype String) is mandatory within that element. Compare with the next rule, if you supplied a Characteristic element, then the name and value are both mandatory within the element.
It is confusing, perhaps, due the unfortunate choice of the same name for the element (data type) and the attribute.
Hope it helps
