The rules for insert and delete are careful to call removeType() only if the
nodes being inserted/deleted can affect the type (that is, if they are
elements, attributes, or text nodes). The rules for replace make no such
provision; they remove the type annotation even if the only effect is to
replace a comment with a processing instruction. It's a minor point, but the
rules should be symmetrical.

removeType() is necessary if either the node being replaced or one of the nodes
inserted in its place is a text, attribute, or element node.
