Internal Subset only: a reference to an undeclared general entity

Note: entity inclusions are placed between a starting 'START--' and ending '--END'. That way you can see if an entity value has been properly resolved, or not.

Reference to external entity part: START--∂--END (value of resolved part is: "External entity stuff.xml with markup inside of it")

Reference to external entity part2: START--&part2;--END -- there is no resource at the URL used in the entity declaration.
