I doubt this very much. The _character_ / codepoint "&x00" is a
different concept to the byte or octet "&x00". Although Unicode
encodings may well involve such a byte value at the level of the raw
wire protocol, they certainly don't allow it as a valid character
(sic, codepoint).

XML, at the level you describe it, is a character stream. In XML the
entity &#0; is a reference to this possible (albeit forbidden) 00
value as a _character_, not just a raw byte.

It sounds as if your problem here is an encoding problem (i.e. a
Unicode problem, not an XML problem), even before it gets as far as
being an XML well-formedness issue. Raw bytes 0f 00 are just bytes
(which might have some correct place in the encoding you're using) but
they're not intended to encode a resultant _character_ of 00, or the
same thing as a numeric entity of &#0;
