Right. The replacement text for ap is


With msg, the parameter entity is included as part of the replacement text
and so the replacement text of msg is

    he said &#39;hi!&#39;

When the entity msg is referenced within the document element, the character
reference is interpreted, resulting in

    he said 'hi!'

Replacement text is never reparsed at the point of declaration.
