I so argue.  It is well-formed, though not valid, XML.  Validity
inherently can't be checked until you've processed everything.
It might be interesting to define the subset of validity that can
be checked on the fly, though.

My first cut at it says that all VCs except the following can be
checked given the full left context (in stream terms, all that
has come before):

[32] Standalone Document Declaration
[56] IDREF
[56] Entity Name (detectable at end of DTD)
[58] Notation Attributes (detectable at end of DTD)

Have I overlooked anything?

I agree with this.
