Not by definition: a non-WF document simply isn't an XML document at
all, and calling it "valid" is no more meaningful than calling the
text of this email "valid".
In any case, I don't understand your example.

References to external entities in attribute values are not WF.
All this means is that a non-validating parser that doesn't read
all the external parameter entities may fail to detect certain WF
violations.
A validating parser, or for that matter a non-validating but
all-entity-reading parser, will correctly reject such a document as
non-WF.
