Does this mean that if complexType B restricts complexType A (perhaps by
making the last particle of the sequence maxOccurs="0"), and complexType C
is derived from complexType B, and complexType D extends from complexType
C, it cannot change the maxOccurs back to 1 for the particle?

What section of the spec explains this?

My concern is that if another schema <include>s the schema with complexType
C defined, the "effective content model"  for C is not the only thing that
needs to be thought about before extending it, but also any restrictions
that have happened in its ancestor types.
