I was one of the proponents of the current decision, and I still think it's
correct, but Terry has a very valid point, that can perhaps be addressed
without changing the basic decision significantly. Can we change the
language to read something like the following:

"If the entity is an external text entity, and the processor is not
attempting to validate the XML document, the processor may, but need not
include the entity's content. [This is what we say currently, but we can
add a new requirement: ]. If the application, either cannot retrieve the
entity, or chooses not to do so, the application must indicate to the user
that data is missing, and (if possible) offer the oppotunity to fetch the
missing data."

I think the following explanation of why you'd rather not be _forced_ to
fetch everything, should be able to stand as-is.
