Summary: Distinguishing between GE's and PE's

Initial Comment:
There is no documented way to distinguish
between a general entity and a parameter
entity in an ExternalEntityRefHandler.
Right now, the undocumented way is to
examine the value of the context
parameter to the handler, but the docs
clearly state that the context should be
considered opaque.

The feature request is to provide a proper,
documented way to distinguish between the
two.

You are right, it is not documented, but it is the right 
way to check the entity type.

Yes, the docs indicate (not clearly, IMO) that context
is an opaque pointer, but checking whether the pointer
is NULL is still OK, since that is not an attempt to
"look behind the curtain".

We need to update reference.html to properly
document this.
