Absolutely, but the reason for that is that the boundaries
can't be reported. If they could, then SkippedEntity()
could be called.

While working on Expat we discussed that potentially we
could insert invalid XML characters into the attribute
value reported to the application, to serve as markers for
the start and end of the entity. (as per user option)
But nothing really caught on.
